    IC5141 CDL in skipping passive devices Reply

    Hello everyone, 

     I'm trying to import a CDL netlist that contains IO pads and logic into IC5141. The issue I am having is that it skips all of the passive devices within the cell. This particular cell has 3 active MOS devices, 3 diodes, and a resistor. CDL in appears to run correctly, but upon checking the schematic, only the 3 transistors are present. Below is the appropriate snippet of the CDL file, my Device Map file, and my ni.log file. I cannot see any reason for the import process to be skipping the passive devices. Please let me know if any additional information or details are needed. 

    Thank you!

     P.S. I couldn't find a way to enclose the text in a code box, so please excuse the wall of text.

     I think you may have to include the following at the beginning of your cdl netlist:

    .PARAM

    *.BIPOLAR
    *.RESI = 1
    *.RESVAL
    *.CAPVAL
    *.DIOPERI
    *.DIOAREA
    *.SCALE METER

    You should also add the resistor in map file


    devMap  := phyres RNPPO_SP
    termMap := PLUS PLUS MINUS MINUS SUB B
