Fix Bug #629 - "XSPICE d_osc failures". The old code has been completely
replaced by a new design that is faster, more reliable and does not
usually insert analog breakpoints.

Add code in ivars.c to look for a SPICE_ROOT environment variable
that gives the location of the ngspice installation. That allows
binaries to be installed in a different directory to the one
compiled in. The spinit startup file is made location-independent
by passing a variable giving the location of loadable modules,
so this fixes Bug #615 -
"spinit contains arch dependent paths, but is installed as noarch DATA".

Add an option for parameters to the xfer code model to be provided
in a Touchstone-format file instead of as a model parameter.
The change to mif_inp2.c allows the "table" parameter to be omitted.

Prevent crashes in udevices.c when malformed U* instances are present. This would happen with incorrectly written U* gates, ff, latches which do not conform to the PSpice specs. Instead, ERROR messages are output which, hopefully, will help a user to debug their subckt.

Tidy up sp_shutdown with Cider.
3 years ago
51b361bbf0
When Cider models are present, a normal batch mode sp_shutdown (for example, ngspice -b cmosinv.cir) will call com_quit(NULL). This cleans up so that valgrind will find no leaks in Cider devices after sp_shutdown. To disable this feature, set the environment variable CIDER_COM_QUIT="OFF". Even though it really does not matter that Cider memory is cleared just before exit, it makes it cleaner for valgrind checks.
