I'm curious how other simulators do on this simple circuit: * switch as negative resistance oscillator SW1 1 0 1 0 SWITCH1 C1 1 0 1n I1 0 1 100u .MODEL SWITCH1 SW VT=2.5 VH=2.475 RON=1 ROFF=10MEG .print tran V(1) .tran 200e-6 uic
The last line (.tran ...) says to run the transient analysis for 200 us, and says nothing about time stepping. It's part of the gnucap test suite. It's a sawtooth oscillator using a voltage controlled switch. Gnucap gives correct results, with default settings, and even with very relaxed settings, but I have not yet seen any other simulator that handles this circuit correctly without fine-tuning with settings, but I haven't tried them all. I can't get Xyce to complile for me, so can somebody else try it? Also .. commercial simulators .. Spectre, HSpice, etc.. _______________________________________________ Gnucap-devel mailing list [email protected] https://lists.gnu.org/mailman/listinfo/gnucap-devel
