SKILL Simulation code

Ashish86

Hi Andrew,

 I have defined a NMos PCell by writing the CDF parameters in SKILL. I now want to write the simulation code for the  same.

 But I am not sure how to write the simulation code. can you give me some written code as an example?

Thanks.

  • Hi Ashish,

    In the SKILL code you posted the first part would create CDF parameters (w, l, width, length and fingers), and then the next part would create the Simulation Information section of the cell's CDF.  For the simulator you would typically see a list of terminals and other parameters to be netlisted (e.g. w, l), here's a brief example for the spectre section:

        cdfId->simInfo->spectre = '( nil
    
        propMapping       nil
    
        namePrefix        ""
    
        otherParameters   (model)
    
        instParameters    (w l as ad ps pd m)
    
        termOrder         (D G S B)
    
        termMapping       (nil D \:d G \:g S \:s B \:b)
    
    )

    This should give you some idea. I've just seen Andrew's post, going to the documentation is a very good idea, in addition to what he said earlier about inspecting a device in analogLib.

    Hope this helps!
