Pcell Parameter based on other component parameters

tesla07

I created a pcell which is basically a layout artwork on different layers so 'M1' is an artwork on layer M1, similarly I have it for M2 ... M7 and the artwork on a certain layer turns on based on component parameters (Boolean type).

Now since this artwork is repeated many times in layout, I want to create another parameter (basically a Tag) which is based on all other parameters so that I can search a pcell with certain selection of parameters (say M1 and M2 only). I don't know how to do this, best option i can think of is a CDF parameter but then again can I write a if statement in Default value section (string type component parameter) to return a string. Something like if M1 and M2 are selected I should get a Tag like "M1_M2"

Please suggest how to do this.

  • Hi Amit,

    The problem is, computing this new parameter won’t help you with existing instances. There are a couple of ways you could generate the property:

    1. In the pcell code you could add a cellView property with the concatenated layer names somehow. However, the Tools->Find menu won’t find that property - so this doesn’t help.
    2. In a CDF callback you could set this other parameter - and then it would be on the instance (and would be searchable). The problem is, that won’t happen for any existing instances - you could get around that by calling the CDF callbacks using CCSinvokeCdfCallbacks or abInvokeCdfCallbacks - you should be able to find that code around somewhere on these forums or on Cadence Online Support.

    Regards,

    Andrew.
