Brian Taylor 5c4352d02f Add __MINGW64__ defines for builds on mingw with msys. 2023-10-28 10:58:15 +02:00
Brian Taylor 3bb6e86015 Add Windows Visual Studio support for the Isotel d_process xspice digital model. The Isotel mixedsim-master/examples/embedded/motorforce C code needs to have minor changes for _MSC_VER defines, and are not included with this commit. The changes relate to using #pragma pack(push, 1)...#pragma pack(pop) around some structs, and setting stdin/stdout in binary mode. It is doubtful that the cfunc.mod will compile on mingw or cygwin since I don't know if they support pipe/fork/exec/spawn calls. The code builds and runs on Windows, Linux, and MacOS. In the future, Giles Atkinson is looking at allowing Xspice models to load shared libraries (.dll, .so) which will avoid creating and communicating with an external program. 2023-10-28 10:58:06 +02:00
Holger Vogt 046be0cdc8 Use the PSP103 model pspnqs103va (including nqs option) 
as this is the standard in the IHP Open PDK.

Holger Vogt efdf332061 Prevent a crash if hash model table was not generated, 
e.g. due to missing valid models.

Holger Vogt 10d7297798 Add cm_cecit(). If the input file could not be opened, stop ngspice. 2023-10-21 15:52:10 +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 39443fafdd Removing unused models takes much more time than keeping them 
for large circuits.

Probably a hash table may help here (t.b.d.).

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.

Holger Vogt 9702557f81 Evaluate function gauss() in B sources. This is required when 
in .model files the tokens 'temper' and gauss() coexist, because
then the B Source function parser is applied.

Holger Vogt eb36084700 re-formatting (indentation, tabs removed) 2023-10-11 00:08:55 +02:00
Holger Vogt 9edf34495e Don't say 'issue in line no. 0', as this 'info' does not tell 
where the line with position 0 really is in the input deck.

Holger Vogt 7c3cb8169c This is a re-write of the PWM generator. 
It is modelled according to the new d_OSC by Giles Atkinson.
Here frequency is fixed and duty cycle is controlled by an
analog input.

Holger Vogt ecb416b800 This patch fixes a bug when shared library uses XSPICE: 
Don't subtract delta twice, when breakpoint is active
and step is rejected.

Holger Vogt e449c894ce Prepend title line by '*' if printed by 'listing r'. 
This allows skipping all pre-processing.

Giles Atkinson a5704c8453 Fix a "make check" failure, by restoring the dollar-1 test to its 
state before a70e708 as that change is no longer needed after 2790fd6.
 2023-09-25 20:20:06 +02:00
Giles Atkinson 2790fd68bb Make the special "noglob" variable work. To preserve previous behaviour 
change the default value from true to undefined (meaning false).
Also fix a misleading comment in glob.c.
 2023-09-25 10:54:13 +02:00
Giles Atkinson a70e708114 Make special interpreter variable "noglob" behave as documented: 
globbing is off by default.  An incompatible change, but previous
behaviour can be restored by "unset noglob" in .spiceinit.

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).
 2023-09-23 17:03:24 +02:00
Giles Atkinson 588116af48 Fix a bug in the "help" command. Some commands have no action function, 
so the function pointer should not be used to detect the end of the table.
Use the command name instead.
 2023-09-23 17:03:19 +02:00
Giles Atkinson 423f9a9db2 Fix a build bug for XSPICE: files generated for code models are 
not removed when doing 'make clean' from release/src/xspice or above.

Giles Atkinson 62471ecede Fix two bugs in cmpp: an unmatched right bracket in cfunc.mod 
causes an infinite parsing loop (mod_yacc.y) and XSPICE macros
are replaced in string literals (mod_lex.l).
