Cdl Export parameters missing

Discussion in 'Cadence' started by Nikolaos Kasparidis, Oct 7, 2004.

  1. Hello,
    I have a problem when attempting to extract a valid schematic using
    File->Export->Cdl in CIW. The schematic contains a custom 2-port
    device(inductor like, made by me) and two pins. The device contains an
    auCdl view (copied symbol). The schematic returns no errors or
    warnings in Check&Save. The device contains some CDF properties which
    I need extracted in the netlist, for example length, number of turns
    (CDF names Length and Turns)

    In the CDF properties of the device under auCdl I give the following
    properties
    netlistProcedure: ansCdlCompPrim
    instParameters: Len T
    termOrder: P1 P2
    propMapping: nil Len Length T Turns
    namePrefix: L
    modelName: [Ind]

    the rest are empty. The results of the netlist for the device look
    like this
    LInd_1 net7 net4 $[Ind]
    net7 and net4 are the pin nets and also the modelName but nothing of
    the other parameters. I believe I have to use the dollarParameters
    somehow, but my attempts were fruitless (the documentation was not
    very detailed on this part). I need somehow the other parameters. I
    have valid extraction setup for spectre and auLvs but need auCdl too.

    Thank you

    LInd_1 net7 net4 $[Ind]
    That's exactly the documented definition of an
    inductor for CDL.
    In my opinion you can not output any additional
    parameters.
    The only thing you can have is a third terminal to
    substrate, but this is optional, I guess.

    Maybe I'm wrong here, if I ,let me know
    how you have managed it to output additional parameters,
    I'm very interested in.

  3. Yes I have checked through the cdfDumpAll and they are lists. I assume
    that CIW makes them a list anyway (I put the values through
    Tools->CDF->Edit). I hope I'll figure something out, because there has
    to be a way to extract the properties to the netlist. If I find
    something, I'll let you know

    Thanks for your time
