    difference between capacitors of libraries Reply

    Hi everybody.

    There is a difference between the Cell Capacitor, the cell mimcap  of Cmosp18 library and Cell cap of AnalogLib ?

    There is a condition to use one rather than another??

    The "cap" in analogLib is a generic capacitor - usually ideal (depending on the parameters yuu provide) - a direct interface to spectre's built-in capacitor.

    The capacitors in Cmosp18 are presumably models of real capacitors for whatever process you're using. These will most likely model non-idealities of the process, and probably have a layout representation too (analogLib can't have physical representations because it is not technology dependent).

    Andrew.
