Remove unused global variable cp_dol.
This also prevents a gcc 13 bug, as cp_dol has been set to '\0'
by -O2 optimization (see

Removing unused models takes much more time than keeping them
for large circuits.
Probably a hash table may help here (t.b.d.).

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.

Handle SIGTTIN and SIGTTOU on Unix-like OSs with X11 graphics.
That makes it possible to push ngspice into the background while
plot windows are open: the windows remain responsive.

title: "`quit` in Interactive Mode."
Also restore terminal state when forcing exit with SIGINT (control-C).

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.

Revert "Add code in ivars.c to look for a SPICE_ROOT environment variable"
This reverts commit 6b0ab44f1e
3 years ago
6b0ab44f1e
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".
