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.

Giles Atkinson 2d0561f386 Allow string-valued parameters to XSPICE device models with no default. 
The code model then sees the value NULL.  Needed for the "family"
parameter on logic models, used by automatic bridge insertion.

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
Holger Vogt 86951501a7 Add eprvcd to the commands which set node names to lower case, 
but not the file names after >
Does not work for manually entered eprvcd commands, where the user
has to provide lower case node names.

Holger Vogt d8505f0069 Make error message more verbose by a hint to the line (fragment). 2023-03-18 14:37:47 +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.
