    Passing multiply parameter (m) into cdl netlist in cell level through cdf parameter edit in symbol. Reply

    Hello,

    I was trying to export a cdl netlist for a memory circuit where I want to replicate the load of seen by the driver for driving one cell (say a cell INV1) is multiplied by adding a cdf parameter "m" into the cell INV1 and assinging m=2,3 or whatever we require. By doing this the simulator actually puts the multiplied load, but doesn't include the multiplied number of cells. (eg INV1<0:3> would actually put 4 inverters in the circuit simulator which would take more time to solve). We we are concerned about the load seen only, we can retain only single INV1 but can pass a parameter m=4 so that the driver now sees 4X load than a single INV1.

    To realize this in schematic, I did edit the cdf parameter "m" in the symbol of INV1. When I do ADE--> Simulation --> Netlist --> Create I can see the parameter "m" being passed into the spectre netlist correctly. But when I do the CDL export throuch ICFB window: FIle--> Export-->CDL for the cell where INV1 is instianted, I don't see the parameter m reflected in the CDL netlist.

    Can anybody point me out to the correct way to do this in the CDL export too?

    Hoping for a timely useful response.

    Thanks in advance!

    Pratap
