Pascal Kuthe f66e0bf2ac implement osdi noise support 2023-11-04 19:36:30 +01:00
Brian Taylor df28fabc42 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. 2023-10-28 11:00:03 +02:00
Holger Vogt 19ebfb1887 Add a code model function cm_exit(const int exitcode). 
This function calls controlled_exit(exitcode) to shut
down gracefully.

Holger Vogt 8ef0aece58 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.

Giles Atkinson 41c61604c5 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.
Discussion on ngspice-users, starting 2023-09-01,
title: "`quit` in Interactive Mode."
Also restore terminal state when forcing exit with SIGINT (control-C).

Brian Taylor 492bb64d92 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. 2023-09-09 23:22:06 +02:00

Francesco Lannutti fe89da2b2c Getting rid of SPARSE for Initial Circuit Matrix creation. Now KLU is totally independent from SPARSE. This opens up the interface for other solvers as well 
SPARSE can still used through '.options sparse', but it isn't possible to switch from KLU to SPARSE and viceversa at run-time

Holger Vogt d4c54123d4 Revert "Add code in ivars.c to look for a SPICE_ROOT environment variable" 
This reverts commit 6b0ab44f1e.
 2023-08-06 16:27:33 +02:00
Giles Atkinson 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".
 2023-07-31 14:29:23 +02:00
Holger Vogt 18911b06b6 re-enable rcheck debug output with WINGUI 2023-07-31 14:27:35 +02:00
Holger Vogt fe3222a118 Add an option nginfo to enable a status report during simulation 
(currently available only with MS Windows GUI version).
 2023-07-31 14:26:40 +02:00
Giles Atkinson 5114d6c2f4 Add an option to the iplot command: -d sets the number of simulation 
steps before the window is shown.  The value can be chosen to
limit rapid resizing when starting and that is used in the PLL examples.
 2023-07-15 11:29:32 +02:00
Giles Atkinson e5a931e537 Improve commands for vector scales. "setscale" can now change 
or clear the scale of an individual vector and "compose" can
explicitly create a vector from XSPICE event node history.
 2023-07-15 11:28:48 +02:00
Holger Vogt 0ee5e3f32a 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.

Holger Vogt b6e9ba20b9 Add another error qualifier to decribe the current policy 
when a doubling token exists (or is created) in the netlist.
 2023-05-27 10:43:40 +02:00
Holger Vogt d53acbed8e Add noise capability to XSPICE code models 
Coded according to acan., AC analysis

MIF_NOI is not yet supported by any code model, so
MIF_AC is used (code models behave like in ac mode,
they are noiseless.

Giles Atkinson 240a2b9406 Add missed file inertial.h. 2023-03-22 14:28:23 +01:00
Giles Atkinson 2643e3b17f New code-model library functions cm_schedule_output() and cm_getvar(). 
To be used in the inertial delay code for digital code models.
 2023-03-22 14:27:35 +01:00
Giles Atkinson c1659a64c3 Change output event setup in evtload.c so that, when making an event call 
to a code model, there is no longer a reference to the value of the event
at the head of the free list.  That allows all such free lists (with the
same data type) to be combined, probably improving performance.
This is in preparation for full implementation of inertial delay for
digital nodes.
