Does anyone know of a program (free!!-downloadable) which I can use to simulate 555 timer in astable mode- I also want to use it to simulate frequency modulation via an input to the control pin 5- I want to see the square waves produced.
ive tried Orcad 9.1 Pspice and I couldn't get it to work
Thanks
