how can i get the input capacitance of a pin

Question · Jul 25, 2006

I design a DAC as an analog IP in a SoC chip. The backend team need the capacitance of input pins to synthesis. I do not know how to get the input capacitance from my layout design. I use Cadence 5033 platform.

Who can teach me how to get the capacitance, and how to make the lef or lib file for backend design.

Thanks a lot!!

You can use captab function in ADE, it can simlate the cap of node for DC.
