Using 16.0, I encounter some problems with ideal gates. No problems with real gates (7400.olb, etc.), though. I understand that Gates.olb provides ideal gates. A simple NAND is enough, to show that it does not work for me. The simualtion (pspice) fails on all accounts, except of the net aliases of the inputs (digital sources).
I really wonder what my mistake is?
can you let us know what tool your question pertains ?
I believe u have the wrong forum
