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.

Upon error, bail out when strict_error is set.

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.
It shall however, exit if the simulation is interrupted due
to an error and strict_errorhandling is set.

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.

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.

Add a predifined variable 'skywaterpdk' to speed up circuit
loading and parsing.
If set, it removes quoting tokens for params. This requires
that Skywater PDK does adequately stick to the ngspice syntax
to put params in between braces. As far as tests go, it does.
It also set the number of nodes for MSO devices to 4, so no lengthy
search is required.
