  • 5f59d76a03 Suppress some warnings from MSVC. Giles Atkinson 2024-03-20 10:43:13 +0000
  • 6ce627e6f8 Tidy d_process/ifspec.ifs so that it works after changes in mif_inp2.c and writ_ifs.c to enforce "Null_Allowed". Giles Atkinson 2023-11-08 10:53:12 +0000
  • 27eda59034 Make the 'Null_Allowed' option for XSPICE code model parameters behave as reasonably expected and as described in the manual. Previously a missing (null) value was always accepted if the ifsspec.ifs file contained a default value, and several of the the included code models worked that way. Where there was a useful default, "no" has channged to "yes". Some models with a look-up table defined by two parameters had such defaults that did nothing useful. Thay have been given useful vector defaults. These changes should not affect previously-working netlists. Giles Atkinson 2023-09-12 16:22:43 +0100
  • 7dd2db904c Change CMPP-related struct Mif_Parse_Value to a union as C99 allows initialisation of any member. Also correct a comment in miftypes.h. Giles Atkinson 2023-09-10 15:50:05 +0100
  • 0152ea92db Support use of vector defaults for XSPICE vector parameters. This answers Feature Request 60 - "Array as default value for parameter". Giles Atkinson 2023-09-10 16:13:14 +0100
  • 8ad759bd66 Use the correct type of hash table for device and model names. This fixes unpredictable failures of commands like "print @some_device". Giles Atkinson 2023-07-29 07:51:12 +0100
  • 673ae5c01d Change the code that makes variables from device/model parameters (spiceif.c) and vectors from variables (vectors.c) so that array and string-valued parameters and the resulting variables are handled correctly. Fix a memory leak in converting array parameters; that requires a change in cplask.c so that CPL devices behave the same way as others. Add a "device" variant of the Compose command so that generated vectors are available in scripts. Giles Atkinson 2023-07-03 18:45:38 +0100

  • 65a91648ef temporary printout of deck Holger Vogt 2024-03-13 17:27:33 +0100
  • 14bf034f28 The lexer incorrectly treats a single '_' '-' '/' as an identifier. The counter used for tmp__ names should be incremented after use. The infix_to_postfix converter now has more checks for invalid infix expressions in LOGICEXP constructs. Without these checks the evaluation of the generated postfix could silently create bad gates which would load but simulate incorrectly. All MicroCap and PSpice libraries and QEI.cir pass their tests.

  • f5c0a1420c Upon a warning on a model issue, ngspice should not bail out, even if strict_error is set, as typically the simulation will run and foreign models often have additional unsupported, but less important parameters. Holger Vogt 2024-03-09 23:41:34 +0100

  • e01290c9a2 Replace the logicexp parser with infix to postfix translation followed by evaluating the postfix. logicexp.c is now shorter and easier to understand and maintain. Also, operator precedence expression parsing conforms to the PSPICE rules. Thus, a & b | c is understood to mean (a & b) | c, for example. Brian Taylor 2024-02-12 16:04:00 -0800

  • a70297e87a Several PSPICE 9.1 evaluation digital libraries contain timing .model statements at the global level for subckts with U* instances that reference those models. By specifying "set ps_global_tmodels=1" in .spiceinit an extra pass inside u_instances() will collect those global timing models for use in subckts. Report errors detected when ngspice parses a LOGICEXP but has not added support for operator precendence. Include a hint of how to fix those errors by inserting parentheses. This error only occurs in 10 of 585 cases in the libraries. Note that inpcompat.c has been saved as a unix filetype. Brian Taylor 2024-01-16 15:29:58 -0800
