Giles Atkinson 9c71db3a72 Fix Bug #607 -
"DC Source with Pulse stops pulsing half way through simulation".
Do not require breakpoints to be hit almost exactly before scheduling
the next one.  That may cause the next breakpoint to be lost.

Giles Atkinson e3b4df6a51 First group of digital code models with improved implementation

2023-03-22 14:27:54 +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.
2023-03-22 14:27:19 +01:00
Giles Atkinson 2d0561f386 Allow string-valued parameters to XSPICE device models with no default.

Brian Taylor 8c69ada5b5 The logicexp example in the PSpice ref. manual has a name with a '+' character (LCN+4). Update lexer_scan. 2023-03-22 14:26:43 +01:00
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
