Brian Taylor 4294f49968 Add more vectors to behavioral 283 circuit. Add tristate buffer circuit which shows glitches until inertial delays are implemented. 2022-12-11 15:25:24 +01:00
Brian Taylor d425beb557 Typo, 2 x1 subcircuits. 2022-12-11 15:20:49 +01:00
Brian Taylor d54c1fc091 Add pindly tristate example. Cleanup error handling. 2022-12-11 15:20:27 +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
Brian Taylor 4e76586b6b Reduce the delays of 'zero' delay gates to 1.0e-11. Add decoder test for logicexpr and pindly. 2022-12-11 15:19:17 +01:00
Holger Vogt 43de22ec24 Update to the examples: enable plotting with option digitop 2022-10-24 17:05:34 +02:00
Brian Taylor 4706c3dea5 Add 74xx283 4-bit adder example from the Micro Cap digital example circuits. Pspice primitives are translated to Xspice and a waveform is displayed using GTKWave. This is a digital-only test. 2022-10-07 13:15:23 +02:00
Holger Vogt e9b5a9a957 aswitch needs two input nodes because gd has been selected for input. 2022-10-07 13:13:38 +02:00
Brian Taylor 7f38ce4ebb Remove debug code. 2022-10-07 12:55:42 +02:00
Brian Taylor 112e47d0d3 This test is equivalent to examples/xspice/xspice_c3.cir and uses Pspice subckts for the divider and nand gate. 2022-10-07 12:53:03 +02:00
Brian Taylor e8dfd16cb2 Add counter test. Check for usage of $d_lo, $d_hi, $d_nc usage with dff, jkff, dltch which will not translate to Xspice. 2022-10-07 12:52:39 +02:00
Brian Taylor f7c519f149 All-digital U* device examples. No a/d or d/a interfaces on the subcircuits. 2022-10-07 12:52:20 +02:00

Holger Vogt b86f7ce14d compare aswitch (with limit=TRUE) and pswitch 2020-10-10 13:54:23 +02:00
Holger Vogt fdc143ce16 Add a limit capability to the code model aswitch 
Example switch-oscillators_inc.cir showed currents up to 3GA
