Passing CDF parameters from instantiated Symbol to Schematic 3 comments

In Cadence, we can pass parameters individually from each instantiated symbol to schematic using Component Description Format(CDF) parameters. Where do I require? Suppose you want to test your design idea, where you require two op-amps with different specifications but want to use same macro model/schematic for both opamps. Suppose you […]
