Giles Atkinson 2db6b529f2 Fix Bug #630 - "pwl if r=last time, simulation never ends".
Allowing a PWL repeat to start at the last time-point makes no sense.

Giles Atkinson f4f2f41940 Fix another error in 9c71db3a72. 2023-07-15 11:12:52 +02:00
Giles Atkinson 9099a922fd Apply a patch from Aleksey Morozov to fix a bug that he identified
and reproduced.  It is the same as Bug #331 -
"XSpice skips digital output point" except that it applies to the
instance queue, not the event queue.

Giles Atkinson 2643e3b17f New code-model library functions cm_schedule_output() and cm_getvar().

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.

Brian Taylor 40a540a2ff Add inertial_delay=true to .model statements generated when U* instances in PSpice library subckts are translated to Xspice. Any other Xspice A* digital instances might have different inertial_delay settings in their models, so potentially there could be a mixture of delay types. For example, if a user wishes to model a DLYLINE using a d_buffer with inertial_delay=false and equal rise/fall delays. 2023-03-22 14:26:18 +01:00
Brian Taylor 164db58404 The intent now is to rely on a variable setting in .spiceinit to control the use of inertial delay XSPICE digital models. This will apply to U* instances in subcircuits which are translated to XSPICE. 2023-03-22 14:25:51 +01:00

R. Timothy Edwards c12296182c The code in src/frontend/subckt.c has a fixed-size structure called table at the top with a size set to N_GLOBAL_NODES = 1005. If the number of items passed in formal and actual exceeds 1005, then ngspice exits immediately with an error.
This patch lets table be reallocated on the fly as needed to accommodate the number of subcircuit arguments, instead of being a fixed value.

Brian Taylor f570b04d6c For unspecified gate delays (logic and tristate gates), which PSpice would consider as zero, set the rise and fall delays to 1.e-12s (the minimum for Xspice). For dff, jkff, dlatch, and srlatch use the Xspice default 1.0ns for rise and fall delays. If the ngspice variable (ps_port_directions & 2) is true, write the translated subckt to stdout, with TRANS_OUT prefix, for debugging purposes. The user could edit and replace the translated subckt if desired. 2023-02-01 17:36:36 +01:00
Holger Vogt 26cf1a7a57 max_align_t is used to examine the largest alignment requirement,
and it is expected to check the alignment value via alignof, not sizeof.

Otherwise, __attribute__((aligned)) can complain as required alignment
being invalid, e.g. on s390x.

Pascal Kuthe acfaf023b3 prototype for Verilog-A integration using OSDI and OpenVAF
This initial prototype is capable of performing DC, transient and AC
analysis. Not all features of OSDI are supported yet and there are still
some open questions regarding ngspice integration. However many usecase
already work very well and a large amount of CMC models are supported.
The biggest missing feature right now is noise analysis.

test: test case for diode DC working with SH

test: add transient analysis to osdi_diode test

test: added docu text to osdi_diode test

test: added test case directories

fix: bug in osdi_load

test: small change to netlist

fix: implement DEVunsetup

test: osdi diode enable all analysis modes

removed netlist

ignoring test results

added the build of the diode shared object to the python test script

deleting old stuff and always rebuilding the shared object

added diode_va.c to the repo

preparing CI

Create .gitlab-ci.yml file

(testing) add res, cap and multiple devices test

feat: use osdi command to load files

Previously OSDI shared object files were loaded from fixed directories.
This was unreliable, inconvenient and caused conflicts with XSPICE.

This commit remove the old loading mechanism and instead introduces the
`osdi` command that can load (a list of) osdi object files (like the
codemodel command for XSPICE). A typical usecase will use this as a
precommand in the netlist:

.control
pre_osdi foo.osdi
.endc

If the specified file is a relative path it is first resolved relative
to the parent directory of the netlist. If the osdi command is invoked
from the interactive prompt the file is resolved relative to the current
working directory instead.

This commit also moves osdi from the devices folder to the root src
folder like xspice. This better reflects the role of the code as users
may otherthwise (mistakenly) assume that osdi is just another
handwritten model.

test: update tests to new command

fix: do not ignore first parameter

feat: implement log message callback

fix: don't generate ddt matrix/rhs in DC sweep

fix: missing linker script

update to osdi 0.3

fix: disable x by default

fix: add missing SPICE functions

fix: update diode to latest ngspice version

feat: implement python CMC test runner

doc: Add README_OSDI.md

fix: make testing script work with python version before 3.9

Holger Vogt f073fb5c05 Consecutive tran and ac simulation may lead to gross errors
when TC or scale is used on the instance line of C and L.
Reason is the missing reset when CKTtemp is called once during each
simulation command. TC or scale is then applied again and again,
a reset is missing.

This patch adds a reset, i.e. the capacitance or inductance is
reset to its instance value in a call to *temp. It fixes bug#594.

Command 'alter' has been tested.

Resistance has not been tackled by this bug, because the line
here->RESconduct = here->RESm / (here->RESresist * factor * here->RESscale);
differs from
here->CAPcapac = here->CAPcapac * factor * here->CAPscale;
in that there is no accumulation of correction factors with here->RESconduct

Brian Taylor 7b5c780043 Fix a memory leak. Cleanup the code a bit. All-digital Pspice subckts with U* devices for most used gates/ff can be handled. More extensive test cases are necessary. Also, interfacing subckts with analog ports is not implemented. 2022-10-07 12:49:46 +02:00
Brian Taylor 96a1b528fd Replace Pspice U* and .model cards with their Xspice equivalent statements. There are still memory leaks which will be plugged next. The .subckts have only digital ports, which will need to addressed for mixed A/D designs. 2022-10-07 12:49:29 +02:00
Brian Taylor 2c3c632349 Add translation of ao/aoi compound gates. 2022-10-07 12:49:06 +02:00
Brian Taylor a2fd346b1a Trial run at scanning cards for Pspice U* devices and models. #define INTEGRATE_UDEVICES to turn it on. No new cards are created yet, just lots of debugging info. 2022-10-07 12:48:51 +02:00
Brian Taylor 9bbcf20584 Add brief usage notes and makefile. asserts will need to be removed after integration is complete. 2022-10-07 12:48:36 +02:00
Brian Taylor b367434c78 Add default zero delay models d0_gate, d0_eff, d0_gff, d0_tgate. Use tprintf. 2022-10-07 12:48:21 +02:00
Brian Taylor 620c15a981 Initial files for translating Pspice u.. instances and timing models into Xspice equivalents. Standard gates, tristate gates, dff, jkff, dlatch are supported. Compound gates and pullup/down are not done. Makefile and frontend/inpcom.c changes have not been finished. These modifications will be needed to complete integration. 2022-10-07 12:47:59 +02:00
