CDL resistor value different the schematic

rdohanyos
When I netlist a CDL from Virtuoso, it evaluates the Rho and squares instead of using the Resistance that is provided in the schematic. Is there a switch somewhere to change this? The netlist value is smaller then the schematic value because the Rho/sq method doesn't take into account the space between the end of the recognition layer and the contacts which actually adds to the resistance. Thanks Rob

  • Hi Rob,

    Presumably you are using auCdl views and the Analog CDL flow rather than the Digital flow (i.e. you have the shell environment variable CDS_Netlisting_Mode set to Analog)? In this case the cell CDF for the resistor in question controls how this cell is output in a netlist, look in the simInfo (simulation information) section for how the cell is written out, what parameters are involved.

    I hope that this helps you.

    Regards,

    Lawrence
