Hi guys,
In my circuit, there is a digital controlled capacitor array, I would like to evaluate the AC response (of the entire circuit) change due to capacitor array's capacitance value change. Meaning that for each capacitance value controlled by digital controlled cap array, I need to perform the AC simulation once. In cadence, how should I do this kind simulation? thank you
Thank you for your quick reply, that might work. but could you please give more detail info? for example, if I use a SAR logic or just a counter to control the cap array. how should I define the digital code into parametric analysis?
thank you
I would build a separate testbench for this AC analysis. Just the switch-able capacitor and a (perhaps verilog-a) control block that selects them.
If you do not like the previous solution, you could also write an ocean script and go thru all the codes.
