Also fixes lots of warning + within ciderlib related to unused variables. + + * Fixed a compile warning in src/frontend/com_history.c when readline + or editline are used. + + * Removed the files src/misc/terminal.h/.c and src/include/terminal.h + The first two were empty and the last just included the second. + The relevant makefile.am files have been updated, so a ./configure + will need to be re-run before building. + + * Fixed problems where printf format was int yet on some systems the argument + is long (due to size_t being long). Fixed by always using long format and + casting to long. Affected src/frontend/spiceif.c and src/misc/alloc.c + This makes obsolete the IS_SIZE_T_LONG macro that defined by configure.in, + now removed -it was not working for all platforms (eg. MacOSX) + + * configure.in - Removed IS_SIZE_T_LONG (see above). Now only test for + ncurses etc., when either Readline or Editline are being used. This will + fix the basic problem of building on MinGW which does not have these + libraries as standard. Fixed the typo in the AC_REVISION() macro. + +2005-05-20 Steven Borley + + * nghelp now uses src/conf.c for consistency with ngspice and ngnutmeg. + Under MinGW the nghelp window is now kept open until a key is pressed. + This allows users to see any error messages before the system closes + the window. + + * src/conf.c now uses PACKAGE_VERSION (was VERSION) and PACKAGE_BUGREPORT + (was hard coded in file to "ngspice-bugs@lists.sourceforge.net"). These + values are set by the AC_INIT macro in configure.in + + * src/winmain.c - changes to fix warning when compiled with gcc + +2005-05-19 Steven Borley + + * Fixed declaration of oflag in winmain.c - fix from Dietmar Warning + + * Fixed compile of makeidx for MinGW. + +2005-05-18 Steven Borley + + * Reverted src/spicelib/devices/restemp.c to previous version. Changes in + this file were intended for temporary debug and should not have been + committed to CVS. + + * Moved isnan() to src/misc/missing_math.c from src/spicelib/devices/dev.c + following suggestion from Dietmar Warning. Also took opportunity to fixed + a compiler warning in dev.c + + * Conversion of files containing non-ASCII characters (German language + comments) to ASCII by Dietmar Warning. + + +2005-05-18 Steven Borley + + * I erroneously omitted a few changes from Dietmar Warning: + Fix to src/maths/cmaths/Makefile.am to exclude test programs that don't + compile under MinGW. Fix to src/spicelib/devices/dev.c to exclude local + isnan() when it exists as a library function. + + * Fixes to src/Makefile.am to exclude programs that don't compile under + Windows (MinGW). Fix to avoid dependence problem with linking in winmain.o + +2005-05-17 Steven Borley + + * Updates configure.in. Notably this removes the need for acconfig.h (the use + of which is deprecated by autoconf). Most of the remaining changes just + tidy with the aim of following guidelines in the autoconf manual. Fixed an + issue with CFLAGS usage and --disable-debug. Some fixes aimed as support + for MinGW (more to follow). + + * Removed acconfig.h (see above for reason). + + * Updated various file to allow build using MinGW. Affected files: src/main.c, + src/nghelp.c, src/frontend/evaluate.c, src/frontend/resource.c, + src/frontend/signal_handler.c, src/frontend/wdisp/windisp.c, + src/frontend/wdisp/winprint.c, src/include/macros.h + These changes mostly supplied by Dietmar Warning. + Highlights: macros used for sigjmp_buf (JMP_BUF), sigsetjmp (SETJMP) and + siglongjmp (LONGJMP); Fixed problem of duplicated definition of BOOL. + Adjustments to allow ngnutmeg to compile with a Windows frontend. + +2005-05-11 Steven Borley + + * Changed line-ending on several files from DOS to UNIX. + + * Translated German in to English in comments for several files + (where the German was simple and meaning clear from the context + - and Babel fish helped too). This also removes the non-ASCII + characters from these files, which was giving problems on + at least one platform. + + * In the above files I have also replaced c++ comment style with + c comments (i.e. // go to /* ... */). + +2005-05-10 Steven Borley + + * Some minor tidy-up as follows: + - Added missing .cvsignore files in many source directories. + - Added #ifdef CIDER...#endif around fields in structure initialisation + of nbjt, nbjt2, numd, numd2 and numos - this is strictly unnecessary + as these devices are only used when CIDER is defined but it keeps + symmetry with other devices. + - Added some extra TRACE debug statments in in the parser + + * Added conditional on the ngspice program to prevent errors when spiceinit + file is used with ngnutmeg (spiceinit.in) + +2005-05-10 Paolo Nenzi + + * src/spicelib/devices/isrc/*,src/spicelib/devices/vsrc/*: added + XSPICE extensions: PHASE parameter and current in isrc. Added AM + transient function (Amplitude Modulation): + + AM (sig_ampl offset_const mod_freq carrier_freq t_delay) + + The waveform will follow: + + value = sig_ampl*{offset_const + SIN(2*PI*mod_freq*(t-t_delay))}* + SIN(2*PI*carrier_freq*(t-t_delay)) + + As an example you can use: + + V1 1 0 AM(10 1 1K 100 1M) + + R1 1 0 1 + +2005-05-09 Steven Borley + + * Added new syntax to the the resistor card to support HSpice style + temperature dependence (from Hitoshi Tanaka ). + Syntax forms now include: + Rxxx n2> TC= + Rxxx n2> TC1= + Rxxx n2> TC1= TC2= + Rxxx n2> TC= + The the first pair are equivalent, and the last pair are equivalent. + +2005-05-07 Steven Borley + + * Added support for the BSD licensed editline library + This includes a work-around to fix a problem found in the current version + of this library (see prompt() in src/main.c). + + * Added and updated infomation in the INSTALL file. + +2005-05-06 Steven Borley + + * Added code by by H.Tanaka for the .global keyword. This is enabled by + supplying the new --enable-dot-global argument to ./configure. + + * Also added configuration for a new --with-editline=yes|no argument to + ./configure for future support of the BSD editline library as an + alternative to the GNU readline library. + +2005-05-05 Steven Borley + + * Fixed a compile problem with Xspice on Cygwin. Still will not link, but + it's a step in the right direction. + +2005-05-04 Steven Borley + + * Fixed issues with the alternate prompt (src/main.c, src/frontent/control.c + and src/include/cpextern.h) - a format problem when used with readline and + a buffer overrun. Also reduced max number of chevrons to 16 and added + at + start when command stack is holding than 16. + + * Translations for German comments provided by Dietmar Warning, to fix + issue with UTF-8 observed on Windows (src/main.c) + + * Fixed readline operation within ngnutmeg (src/main.c). Also include some + minor tidy-up to avoid some compiler warnings. Updated copyright date + for --help. + +2005-04-29 Paolo Nenzi + + * src/frontend/inpcom.c: end-of-line comments starting with + the "$" (dollar) sign can be confused with a variable. To + avoid this, the new syntax for such and-of-line comment is: + $ (the space is mandatory). + Patch sent from Steven Borley . + + +2005-04-26 Paolo Nenzi + + * src/main.c, src/frontend{inp.c, nutinp.c}, src/include/defines.h: + New logic for ngspice initialization (patch from Steven Borley + ): + + Load the standard start up file 'spinit' + Then look for '.spiceinit' in current directory + If this fails look for 'spice.rc' in currect directory + if this fails the check the HOME environment variable + if HOME is set then: + Look for for '.spiceinit' in user's home directory + If this fails look for 'spice.rc' in user's home directory. + + Fixed a memory leak in main.c + + * src/include/{complex.h, fteext.h, ngspice.h, sperror.h}: + code cleaning and removed some warning (patch from Steven Borley). + +2005-04-25 Paolo Nenzi + + * src/frontend/numparam/{general.h, numparam.h, nupatest.c, + spicenum.c, washprog.c, xpressn.c}: Applied patch from Steven + Borley . The patch removed the numparam + support for end-of-line comments and moved it into frontend code. + Line buffer for numparam is increased from 250 to 1000 to accomodate + large model cards. Fixed compilation on Cygwin and MacOSX. + + * src/frontend/subckt.c: numparams, once compiled in, must be + enabled, during interactive session, using "set numparams".

All the following can be used to start a comment: + ; for compatibility with PSpice + $ for compatibility with HSpice + // like C++, and as per numparams + -- as per numparams + This was a full re-write of this code, not a conversion of the + numparams code. It is not dependent on the numparams library. + + * src/frontend/resource.c: Fixed a compile bug under window & cygwin + (patch from Steven Borley). + + * src/frontend/plotting/x11.c: Applied patch from Steven Borley. + + * src/spicelib/analysis/cktsetbk.c: Added some code to track + breakpoints (you need to define TRACE_BREAKPOINT macro). + + +2005-04-16 Paolo Nenzi + + * src/frontend/{subckt.c, inpcom.c}, src/frontend/numparam/{general.h, + mystring.c, readme.txt, spicenum.c, xpressn.c}: Applied patch from + Steven Borley that fixed numparam + library. Patch description follow (extracted from Steven's + message): + + > Fixes problem with logfile not being opened before we have + something to write to it, + > Renamed round() and trunc() to avoid clash with functions in + math.h, + > Numparam now only stops execution when it finds errors, + > Added some debug tracing (normally off), + > Added some debug tracing (normally off), + > Fixes a #ifdef that had a typo and thus stopped numparams, + working, + > Renames a local variable to avoid confusion (of the + developer/maintainer), + > Fixes the renumbering of lines from a .include file. + + * examples/numparam/{example.cir, pintest.cir,pin.mod}: added + netlists sent with Steven's patch. + + + * src/frontend/subckt.c: Added fix sent by Hitoshi Tanaka + . Now nodes starting with the letter "v" + in subcircuits are translated correctly (as internal nodes) + and not as voltage sources v. + + * src/xspice/cmpp/pp_lst.c: malloc did not consider the null + terminating character in "path". Applied patch from Mac OSX + patch file maintained by Khairulmizam Samsudin . + + * src/xspice/icm/makedefs.in: Mac OSX requires different flags + for shared libraries linking. Applied patch from Mac OSX patch + file maintained by Khairulmizam Samsudin . + +2005-04-06 Paolo Nenzi + + * src/frontend/subckt.h: Since inp_numnodes has been declared static + the prototype has been removed. + +2005-04-04 Paolo Nenzi + + * src/frontend/subckt.c: Applied patch from Steven Borley + that fixes a bug in model + name translation that shows in nested subckts reported by + Hitoshi Tanaka (for which he sent a patch that + was supersed by Steven's one). + + * configure.in: As Stuart Brorson suggested now the garbage collector + library is compiled only on explicit request by the user. + +2005-03-20 Paolo Nenzi + + * src/spicelib/analysis/cktntask.c: The default parallel + multiplier (m=1) for mosfet levels 1, 2, 3 and 9 was not set + in interactive analyses. Applied fix sent by Steven Borley + . + + * Changed value of trtol to 1 when xspice extensions are compiled + (as in xspice source code). + +2005-03-17 Paolo Nenzi + + * src/main.c: Applied patch sent by Steven Borley + that removed the duplicate + declaration application_name and gnu_history_file, removed the + "static" keyword in shutdown() and set NULL as return value in + function prompt() when non prompt is passed to readline(). + + * src/ngspice.txt: Applied patch sent by Steven Borley + that fixed a few errors that + corrupted text output. + + * configure.in: Applied patch sent by Steven Borley + that fixes compiler warnings + on MAC OSX (related to the linking order of X libraries).

This new script + adds support for different architectures (MINGW32, Linux, SunOS). + + * src/spicelib/device/vbic/vbicpzld.c: Corrected an error in pole-zero + routine. Dietmar Warning sent the fix. + +2005-03-07 Paolo Nenzi + + * src/spicelib/devices/bsim4/b4ld.c: commented out NEWCONV section. + +2005-03-06 Paolo Nenzi + + * src/spicelib/devices/bsim4: removed uninitialized variables in model + files. + + * src/spicelib/analysis/dctrcurv.c: Dietmar Warning + has changed the way the lst point in a dc + sweep is computed. This new scheme is more accurate. + + +2005-02-28 Paolo Nenzi + + * DEVICES: Updated (again) changing BSIM4 level from 60 to 14 since + older model revisions are not yet in ngspice. This is consistent + with model developers: newer models are compatible with older ones. + + * src/spicelib/devices/bsim4/: updated to revision 4.4.0 with "m" + parallel multiplier enhancements. Thanks to Mick Tooher + and Dietmar Warning for + this update. + + * tests/bsim4/: updated test files for bsim4 4.4.0. The old files have + been replaced with new ones coming from BSIM4 site. There are new + tests: (*_gedl*) and ro_17.cir. + +2005-02-25 Paolo Nenzi + + * DEVICES: Dietmar Warning (warning@danalyse.de) provided me an + updated and corrected version of this file. + +2005-02-08 Paolo Nenzi + + * src/frontend/subckt.c: modified the file with the one supplied by + Dietmar Warning's (warning@danalyse.de). This fix the bug that + caused ngspice to crash with long subckt lines. + +2004-09-05 Paolo Nenzi + + * src/spicelib/devices/jfet/jfet.c: model type (njf or pjf) was + defined as input/output parameter. Now is an input-only parameter, + as in other models. + + * tests/jfet/jfet_vds-vgs.out: Corrected the output after the change + in jfet.c. With the old code the number associated to njf or pjf + (meaningless) changed each run of ngspice and caused the check + process to fail. + + * src/spicelib/devices/mesa/mesa.c: model type was reported + incorrectly. Declared parameter vt0 as "redundant", since it has + the same meaning of vto. + + * tests/mesa/mesa11.out: changed test file output according to + changes in mesa.c. Now model type ic correct. + + +2004-09-01 Paolo Nenzi + + * src/conf.c: Modified bug reports address. Now it points to a + mailing list dedicated to bug reports. + + +2004-08-29 Paolo Nenzi + + * src/fronted/aspice.c: Added a define for FreeBSD (from + FreeBSD ports archive). + + +2004-08-22 Paolo Nenzi + + * src/xspice/enhtrans.c: Removed code introduced by Stuart Brorson to + limit parsing of POLY statements to dimension 2. Now functions + returns a copy of the error strings that i freed by higher level + code once processed and write the error on the expanded netlist (as + comments) instead of expanded lines (this fixes a segmentation fault + since INPpas1() does not check if the returned line is not null and + makes expanded netlist more informative). + +2004-08-20 Paolo Nenzi + + * src/frontend/{gens.h, gens.c, device.c}: Committed another Vera + Albrecht's patch for the "show" command. This closes the bug + definitively. + + * src/include/{cktdefs.h, dgen.h, ftedebug.h, missing_math.h, + ngspice.h, noisedef.h, sensdef.h}, + src/spicelib/analysis/{ckt.h, ckti2nod.c}: committed Vera + Albrecht patch to remove some compiler warnings. + + +2004-08-16 Paolo Nenzi + + * src/frontend/{device.c, gens.c}: Committed Vera Albrecht's patch + to the "show command" I closed on 2004-08-13. Vera's patch is + better. + + +2004-08-15 Paolo Nenzi + + * configure.in, src/spinit.in: Added a variable in configure.in + to decomment codemodels lines in spinit if --enable-xspice is + issued in the configure phase. It is a hack but works. + +2004-08-14 Paolo Nenzi + + * src/main.c: The code for -o option contained an error that + prevented the correct operation of output redirection. The + masking #ifdef has been changed to #ifndef. + +2004-08-13 Paolo Nenzi + + * src/frontend/device.c: "show" command leaked 28 bytes for each + group of words since an allocated pointer in line 33 of gens.c + was never freed. It is not possible to free allocated memory + using that pointer since it is used and its value altered. I + used "listdg" copying original pointer value to it and freeing + memory using "listdg" instead. There were sone "tfree" that + caused problems for incorrect inputs, I have removed them and + tested against some bad syntax. Results shows no leaks. + + * src/spicelibe/devices/{res/resparam.c, cap/capparam.c, + ind/indparam.c}: Fixed a bug introduced with m and acResistance + parameters. Since show command works as soon as a circuit is + loaded, before any call to DEVsetup or DEVtemp is made, some + parameters, in this early call showed incorrect results. + Simulations are not affected by this bug, but it is annoying. + Now principal parameters are display correctly. + + * src/spicelib/analysis/cktncdump.c: fixed a typo that prevents + compilation on some systems. + +2004-08-09 Paolo Nenzi + + * Updated and corrected test files in "tests" directory. Added + "examples" directory. + + * src/spicelib/devices/bsim3/b3set.c: Added Dietmar Warning + patch to solve a bug that shows up when + acm=2 was used. From Dietmar's mail message: + if we use the acm=2 option we must set the nrd and nrs + defaults to 0. + + * src/spicelib/devices/mos3/mos3temp.c: As suggested by Dietmar + Warning I removed the >1um limit for the + model. + + +2004-07-08 Paolo Nenzi + + * Applied Al Niessner negabyte patch + that removed all compiler warnings. + + * configure.in, src/xspice/icm/makedefs.in, tests/Makefile.am, + xgraph/aclocal.m4, xgraph/configure.in, xgraph/configure: updated + configuration files for autoconf V2.59 automake V1.8. + +2004-07-05 Paolo Nenzi + + * src/frontend/resource.c: added __APPLE__ for mac osx support as in + patch sent by Khairulmizam Samsudin + + * src/spicelib/parser/inpdomod.c: fixed some typos as in patch + sent by Khairulmizam Samsudin + +2004-06-22 Paolo Nenzi + + * src/spicelib/devices/vbic: Vbic code updated. Thanks to Dietmar + Warning (warning@danalyse.de )now we have the four terminal + version of the VBIC model. The old three terminal version has + been discarded. + +2004-06-21 Paolo Nenzi + + * src/frontend/subckt.c: patch from Stuart Brorson + . This patch adresses the following + problem (as written by Stuart): + Modified modtranslate and devmodtranslate to fix bug noticed + by Liu: codemodel names called out in the device instantiation + line ("A1 1 2 3 4 lim") were not translated correctly if they + were invoked inside a .subckt. Fix involved explicitly adding + code to handle "A" device types when translating the line. + SDB 6.18.2004. + + +2004-05-30 Paolo Nenzi + + * src/frontend/subckt.c: patch from Dietmar Warning + (warning@danalyse.de) to fix memory errors when using very + long model card. + + src/spicelibe/devices/vbic/vbicsetup.c: patch from Dietmar Warning + (warning@danalyse.de) to fix vbic behavior. + + +2004-02-14 Paolo Nenzi + + * Trimmed the autoconf interfaces. Added dummy ".out" files + into many tests subdirectories and modified many Makefile.amS. + +2004-02-05 Paolo Nenzi + + * src/spicelib/analysis/cktntask.c: Bug: not all the values + of TSKtask structure were copied and got a correct default + value. The bug showed as an infinite loop in gmin stepping. + +2004-02-10 Paolo Nenzi + + * src/frontend/inpcom.c: Applied patch from Dietmar Warning + to solve the bug discovered by Jelle Haandrikman: wrong + subcircuit expansion when leading spaces are present in the + subcircuit netlist. + +2004-01-28 Paolo Nenzi + + * configure.in: changed version to rework15. + +2004-01-27 Paolo Nenzi + + * configure.in: changed version to rework15-pre3 and other + small changes for release. + + * AUTHORS, FAQ: Updates + + * src/spicelib/devices/bjt/bjtpzld.c, + src/spicelib/devices/bjt2/bjt2pzld.c: there was an error + in the pole-zero routine.

This involved + lots of changes in src/xspice/mif and src/xspice/enh. + Particular changes were made in: + -- MIF_INP2A: re-arranged logic to fix parsing problems. + -- two2three_translate: fixed some stupid pointer problems. + -- etc. + + * Revamped src/xspice/icm/ and src/xspice/icm/icm_spice2poly + directories to enable build of POLY codemodel. + Makefiles were fixed, and some stuff was added to enable + cmpp (from SPICE Opus) to build the codemodel precursors + correctly. (Note that you need to download and install + SPICE Opus to rebuild the codemodel stuff. See + src/xspice/icm/README for more details.) + + * Hacked Makefile.am's for much of the directory hierarchy, + particularly for src/xspice/icm and + src/xspice/icm/icm_spice2poly to build the POLY codemodel + correctly. Note that top level make still doesn't detect + changes in the xspice hierarchy; read the NOTES file for + a workaround. + + * Added a SPICE netlist incorporating vendor models with + SPICE2 POLYs in tests/TransImpedanceAmp/. Running this + model successfully demonstrates that you have built the + XSpice POLY codemodel correctly and that life is good + . . . . + + * Moved #define TRACE out of src/ngspice.h and made it + a compiler option (-DTRACE) invoked in src/Makefile when + making spice.o. + + 2003-05-02 Stuart Brorson + + * Added #define TRACE to main.c for use in debugging. + Added lots of printf's in the code which are turned on + by defining TRACE. This is used to help figure out what + the program is doing at each step . . . . . + + * Added lots of comments all over the source tree. + This should help explain what the prog is doing for + future hackers. + + * Fixed parser to allow POLY attributes in dependent + sources (major changes in src/frontend/subckt.c, as + well as move location of call to ENHtranslate_poly in + src/frontend/inp.c) + + * Fixed bug in device init files + (src/spicelib/devices/*init.c) + so that Deviceinfo structures operated with XSPICE. + + * Fixed nasty malloc problem in src/xspice/mif/mifgetmod.c + which casued frequent segfaults (when compiled with XSPICE). + + +2002-01-03 Paolo Nenzi + + * acconfig.h: added define needed for Windows and some aesthetic + rework (from Holger Vogt patch). + + * configure.in: added macros to handle windows related + issues (Holger patch and me). + + * INSTALL: added documentation on ngspice compilation under + Windows (Holger Vogt patch). + + * Makefile.am: added Windows compilation code (Holger Vogt patch and + me). + + + +2001-12-05 Emmanuel Rouat + + * configure.in: removed (unnecessary) macros to handle GNU getopt + (I'm an idiot!) + +2001-12-04 Emmanuel Rouat + + * configure.in, main.c: Forgot a bit to handle GNU getopt correctly + +2001-11-25 Emmanuel Rouat + + * configure.in: New way (cleaner) to handle GNU getopt. + +2001-01-21 Paolo Nenzi + + * bsim3soi_dd/*: BSIM3SOI (DD) support added as level 11.

Also: assertions are enabled by + default. + + * src/include/smpdefs.h, src/maths/sparse/spsmp.c: SMPmatrix is + now a typedef for void, instead of char. Updated all function + declarations to match this. Also added function prototypes not + previously mentioned in src/include/smpdefs.h. + + * src/include/complex.h: Updates of cast from char * to void * + + * src/analysis/cktsens.c: Matrices cannot be created non-complex. + Also added a check to detect an error condition on delta_Y = + spCreate(...). + + +2000-06-27 Arno W.

Peters + + * src/include/fte*: Broken header files into smaller pieces. This + avoids long recompile times as less needs to be rebuilt on changes + to the header files. Adjusted all callers to use the new header + files. Left a warning message in the header file to indicate its + obsolescence. You will see this message when compiling. + + * src/frontend/*: Reorganized part of the frontend commands into + their own source file. Moved plotting parts into new plotting + directory. + + * src/devices/*: Removed all RCS log and rcsid from the devices + source files. They only give extra clutter and all the + information you need is available through CVS. + +2000-05-04 Arno W. Peters + + * src/maths/ni/nipzmeth.c: Corrected an overeager deletion. + +2000-05-03 Arno W. Peters + + * source tree: removed most of `#ifdef notdef' and made converted + some function calls from K&R -> ANSI. + +2000-05-01 Arno W.
