How to netlist the RWIDTH and RLENGTH properties of parasitic resistors in microns.

Version 2

     

    In order to generate PEX netlists with the properties of the parasitic resistors: 

           

       such as:  RWIDTH, RLENGTH, and RLOCATION

     

      

    expressed in units of microns,

      

    use the RSCALE optional keyword to the PEX NETLIST rule file statement.

     

      

    As described in the SVRF Manual:

     

      

       RSCALE value

       An optional keyword set, where value is a scaling factor that changes parasitic resistor

       properties, such as width, independently of device properties. The default value is 1.

     

      

    In the Calibre Interactive PEX GUI

     

      

    this setting is found under:

     

      

       PEX Options > Netlist > Advanced > Scale parasitic resistor properties

    Intentional device property units can be adjusted using the

        

        scale

        

    Optional keyword to the PEX NETLIST rule file statement.

        

    As described in the SVRF Manual:

        

    The optional string scale must be a poritive floating-point number and may be a variable.

    It specifies the size multiplier (in units of meters) for the L, W, A, P, AS, AD, PS, and

    PD parameters of MOSFET, diode, and JFET devices. Set scale to 1e-6 meters to render the

    parameters in microns; areas are then in square microns. The default value is 1.

        

    In the Calibre Interactive PEX GUI

        

    this setting is found under:

        

       PEX Options > Netlist > Format > Size multiplier for length units (in meters):
