    IC testing board/software?

    In general, you can apply and see patterns if you use logic analyzer. But, it depends on your signal conditions, such as votage, slew rate, freq.... I don't think I have general document. I read only manuals if it is needed. Using LA is not hard at all. If you give a try, you will see right...

    IC testing board/software?

    Hello. I am a student working on digital VLSI design. I am always wondering if there is any testing board or tool kit that can test my chips. What I usually do is to build a PCB board and socket after I get the packaged chip. And then I use logic analyzer, oscilloscopes and pulse generators to...

    how to run transient simulation with time varying resistance

    spice time varying resistor Thank you for replying! I meant the simulation using "Virtuso Analog Design Environment". I need to run a transient analysis. but I dont know what function or what variable gives the time during the transient analysis. If I can access the time, then I would be...

    how to run transient simulation with time varying resistance

    transient simulation dc source Hello. I want to run a simulation using cadence(icfb). The simulation should show time transient result with a time varing resistor value. Basically, I want to assign the value of resistor as res = sin( w* time) + some offset. Is there any way to do this? The...
