Creating a symbol from a .scs file

samer1

I have a veriglog A model for a device. Earlier, I used to create a symbol from the verilogA model directly and all values preceded by "parameter" in the code would show directly in the CDF list of the symbol.

Now, I have an scs file that includes the verilogA model in it. I want to be able to create a symbol for that scs file and be able to include the scs file from ADL (model setup)?

I tried to use one of the devices in the analogLib "nmos" and include my scs file name in the CDF list but did not work as intended. 

Can someone help with that?

Thanks

    There is no built-in, automated function to read the scs file and generate the symbol. You can do it as follows:

    a. Assuming that your scs file looks like:

    subckt myCell A B C
    ...
    ends

    b. Create a schematic with pins A, B and C
    c. Generate a symbol from the schematic
    d. Delete the schematic
    e. Copy the symbol view as "spectre" view
    f. In "CIW: Tools->CDF->Edit CDF" for the cell, go to spectre simInfo and add "A B C" as the "termOrder"
    g. Set the "componentName" as "myCell"

    You can now use the symbol in your schematic. Include the scs file as one of the model files during simulation.
