Holger Vogt c6efc6bc9c Send 'refernce value' to stdout, not to stderr 2023-05-27 10:43:16 +02:00
Giles Atkinson ad5bb9eb8d 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.

Holger Vogt d53acbed8e Add noise capability to XSPICE code models 
Coded according to acan., AC analysis

MIF_AC is used (code models behave like in ac mode,
they are noiseless.
