hi everyone i usually simulate my circuits in orcad capture.but there are times when i have to use ICs in them too e.gTL 494 in a switch powersupply.i cant find most ICs in the libraries given.can someone help me out here.if they are there then in which libraries should i look for them? also sometimes u also want to put somthing programmable in ur circuit like a microcontroller.is it possible to simulate such circuits in pspce? thanx
