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.

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.

linked model list modtab. The time used here grows approx.
quadratically with the number of models. If the numbers get large,

Therefore the linked list modtab has been enhanced by a hash table
modtabhash, which allows linear search time and makes simulation
of a 200k transistor circuit with IHP PDK possible. Already
the setup time for 15k transistor circuits has been reduced.

Add a control language function cvector, to create a complex vector.

Let vec1 = cvector(50)
will generate a complex vector, with the real part values
increasing from 0 to 49, the imaginary values are set to 0.
Useful in ac loops to store result data.

Always propgate any individual scale for a vector that appears
...
in an expression, resolving conflicts by matching length and warning
only when making an arbitary choice. One effect of this is that it
is now possible to mix analog nodes with offset digital nodes
(an expression like dvalue+6) without a warning and get a correct plot.

Add inertial_delay=true to .model statements generated when U* instances in PSpice library subckts are translated to Xspice. Any other Xspice A* digital instances might have different inertial_delay settings in their models, so potentially there could be a mixture of delay types. For example, if a user wishes to model a DLYLINE using a d_buffer with inertial_delay=false and equal rise/fall delays.

The intent now is to rely on a variable setting in .spiceinit to control the use of inertial delay XSPICE digital models. This will apply to U* instances in subcircuits which are translated to XSPICE.
