How to set the order of a PCell's Parameters?

aakhavan

In Cadence 5, the order of the pcells parameters in the Create Instance form was set by the order of the parameters in the pcDefinePCell function. However, using the same code in Cadence 6.1.5 results in the parameters being in a seemingly arbitrary order in the Create Instance form. Has anyone experienced this or found a work around?

  • Thank you both for the help. I'm running into a different problem now-
    My parameters in the pcell definition are as follows:

    (
    (NX int 1)
    (NY int 2)
    (B1 boolean "FALSE")
    (B2 boolean "FALSE")
    )

    I'm using the code from here to generate the cdf. It works great, except the ordering is incorrect. If I take the reverse() out, the booleans are in the correct order, but I end up with:

    NY, B1, B2, NX

    Instead of the correct order. Looking at the cellview: cv~>parameters~>value~>name shows the same, incorrect order. I can fix this by manually coding the CDF, but I'd like to avoid that. Any ideas why it's throwing off the order?

     Thanks.

     

    Edit: I hacked around this by manually adding the cdf for car(reverse(cv~>parameters~>value)), then running the foreach() loop on reverse(cdr(reverse(cv~>parameters~>value)). This will work assuming the first one is always shifted last for some reason. I'd still appreciate some input though!
