Hi,
I design an ic using an opamp cell from CDK, but the CDK can not do the post layout simulation including the opamp cell, my quetion is:
1. I don't want to design the opamp by myself, is there any problems for using the opamp cell from CDK?
2. what is the postlayout mainly for? I think it is for paracitics capacitor and resistor, is it right?
3. the working frequency is less than 10kHz, must I do the post layout simulation before tapeout?
Thanks in advance
