Giles Atkinson af31904f99 The previous fix for Bug #467 - ".OPTION INTERP has accuracy issue" 
(359e3d46) updated variable timeold inside a loop so that
all interpolations after the first caused division by zero.
That caused the xspice/delta-sigma example to fail.
Set the variable once at the end of the function.

Giles Atkinson 81351555da Mention the vlnggen script and Verilog-controlled XSPICE models. 2023-12-19 14:27:12 +01:00
Giles Atkinson ffcf3b24d9 Improve efficiency and irreversible CM support in EVTcall_hybrids() by 
halting calls to code models as soon as the timestep is chenged.
This should have been included in 508fad0f55.

Check for at leat 4 tokens (name, n1, n2, val/model/...).
If the instance has not been set up correctly, bail out, prevent crash.

Giles Atkinson d82f948832 Fix a crash found by Brian Taylor: when .plot attempts to plot digital 
node history, interpolation may produce an infinite value at digital edges.
Remove vertical edges when interpolating and make some other improvements:
do not calculate a polynomial approximation for unused frames;
center the target x-value in the frame; and do not propogate a reduction
in degree to later frames.

Giles Atkinson c18447f9f5 Add the support files for co-simulation with Verilog code 
compiled by Verilator.  Also add script files to Visual Studio builds
that are already installed by the Makefile builds.

Giles Atkinson a92c569b72 Prevent some strings being mis-recognised by strstr(), including 
one that causes a false error message from the vlnggen script.
 2023-11-27 17:17:21 +00:00
Giles Atkinson 597268cc26 Treat input files names passed a start-up the same as those entered 
as commands or called as scripts: search for them using $sourcepath.
 2023-11-27 17:16:55 +00:00
Giles Atkinson 07ce9c788e Recognise *ng_script_with_params" in the first line of the first 
program input file to mean that the file is a pure interpreter
script that receives any remaining command arguments.
In winmain.c ensure that the argv array is NULL-terminated
and tidy some code.
 2023-11-27 17:06:39 +00:00
Giles Atkinson 89851872ed When substituting interpreter variables, allow '$' to be part of 
the variable expresstion only within '[]' or '()'. That lets
forms like "$a$b" to be treated as two substitutions, not one.

Giles Atkinson 3ba314d4bc New interpreter commands strstr, strslice, fopen, fread and fclose. 2023-11-27 14:58:01 +00:00
Giles Atkinson 566e2938f4 Add XSPICE code model d_cosim, a generic adaptor for digital cosimulation. 2023-11-27 14:50:21 +00:00
Giles Atkinson 12fe7b90c4 Add new code model function cm_irreversible(). This may only be 
called from an XSPICE code model's INIT call and has three effects:
the instance is treated as "hybrid" even when it does not use both
port types; its position in the hybrids array is adusted; and it
is explicitly notifed when called just befoore the end of an
analog time-step.
 2023-11-26 18:30:53 +00:00
Giles Atkinson 34e6c4abea Convert XSPICE's hybrid_index array to instance pointers. 
That simplifies code and will be needed for irreversible code model support.
 2023-11-26 18:29:23 +00:00
Giles Atkinson 508fad0f55 In dctran.c, call EVTcall_hybrids() (which then calls a subset of 
code model instances) only when the current timestep was successful.
That is efficient and means that code models may rely on such calls,
for example a co-simulator may safely advance to the end of the timestep.
The function cm_irreversible() that is mentioned in a comment will be
added in a later commit.
