How to control units of $X and $Y locations in the xRC/xACT-3D extracted netlist

Version 1

    When running xRC or xACT-3D, the $X and $Y locations of the parasitics can be specified by adding the keywords :

     

     

    -RLOCATION for resistor locations.

    -CLOCATION for capacitance locations.

     

    Normally the locations are specified in the units( database units / precession), which is typically microns.

    To specify a different unit for describing locations, the keyword :

     

    -COORDSCALE Value ,can be used with the PEX NETLIST command. Where;

     

     

    -Value is a scaling factor to report the coordinates in.

     

    For example;

     

    -If value is reported to be 1, coordinates will be reported in meters.

    -If value is reported to be 1e-6, coordinates will be reported in microns.

     

    An example would be :

     

    PEX NETLIST "test.dspf" DSPF SOURCENAMES RWIDTH RLAYER RLOCATION CLOCATION COORDSCALE 1e-6
