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

Brian Taylor b142be7fde Add behavioral (LOGICEXP, PINDLY) test for 283 circuit. There are glitches in the simulation for some of the s* outputs. Probably due to not having inertial delays. And why not set 'zero' delays as close to zero as permitted by XSPICE. 2022-12-11 15:19:39 +01:00
