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.

called from an XSPICE code model's INIT call and has three effects:

analog time-step.

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.

Sparse 1.3 is the matrix solver if no option (sparse or klu) is given.
...
KLU is selected by 'option klu'
If both 'option klu' and 'option sparse' are given,
the last one executed determines the solver.
'option sparse=0' de-selects spares, i.e. selects klu.
'option klu=0' de-selects klu, selects sparse.
'option klu=1' has the same meaning as 'option klu'.
'option sparse=1' has the same meaning as 'option sparse'.

Restore the deleted unused params to be backword compatible. Handle the case where the d_process instance has a null in vector, so that N_din is zero. This allows the model to be just a pattern generator. Add include to cmproto.h to avoid a forward ref. to an enum type.

During setup of the models thre have been search scans in the
...
linked model list modtab. The time used here grows approx.
quadratically with the number of models. If the numbers get large,
e.g. with the IHP Open PDK, setup time make simulation impractical.
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.

By default, use the shortest typical delay estimate. This makes the digi_74LS90_74LS42.cir testcase for bug641 behave almost the same as MicroCap 12. In ngspice and MicroCap, the only signal with a glitch is not_y8. The other not_* signals look the same. Setting ps_use_mntymx in .spiceinit will change the delay estimates. See the function set_u_devices_info in src/frontend/udevices.c for the various settings of ps_use_mntymx.

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

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".
