Pascal Kuthe 5223f4b27d fix(hicuml2): ensure flicker noise power is always stored in state vec 2023-11-04 19:36:30 +01:00

Brian Taylor 09f070f582 Error handling improvements in cfunc.mod. Ensure that d_process.h wiil always respond to version and interface checks sent from sendheader. This is needed so that the pipe reads in sendheader do not cause Windows to hang when the interface version and in/out counts do not match. This hang was the cause of errors not being reported and the Windows gui hanging. Startup and header checks are now detected in cm_d_process, and the simulator will run but with runtime errors since a d_process model cannot be completely instantiated after initial errors. It would be good to find a means of gracefully halting the simulation run. 2023-10-28 11:00:33 +02:00
Brian Taylor 8c72a76844 Another attempt at clean up of error handling and reporting. It's OK on limux and cygwin, but Windows VisualC is being stubborn. I would prefer not to have to call exit(1) just for Windows, since then nothing is reported and the gui disappears in a puff of smoke. Even without the exit calls nothing gets reported with the Windows gui which will hang when there are errors detected by d_process. 2023-10-28 11:00:28 +02:00
Brian Taylor 4eae039779 Add modifications note. 2023-10-28 11:00:23 +02:00
Brian Taylor 4530cde8e2 Use Xspice cm_message_send to report errors rathen than printing to stderr and calling exit. When a d_process model has errors found in start(), sendheader(), and dprocess_exchangedata() these are reported, but if the model is run a SIGINT is raised. There must be a better way of stopping the simulator. 2023-10-28 11:00:18 +02:00

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
Brian Taylor 307ba1985b Remove unused reset_state param; do not allow null in and out, so there is at least 1 input and 1 output. 2023-10-28 10:59:52 +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 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 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.

Don't subtract delta twice, when breakpoint is active
and step is rejected.
