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.

  • Thanks for your reply Lawrence, Let me explain the problem in detail.

    I have created a pcell with 13 boolean Parameters, 1 for artwork in every layer (say from layer M1 ---- layer M7 + layer V1 ---- layer V6). So when I check M1, the artwork for M1 shows up and when I check M1 and M2, the artwork on layer M1 and M2 shows up. This way I can make many artwork for all possible combination. Now in my layer this cell with multiple artwork is present and I want to be able to select them using search tool. lets say my top layout has pcell with both M1+M2 checked along with pcell with just M1 parameter checked. Now I want to be able to search and select only M1+M2 and not the one with M1. As per my understanding I need to create another parameter with string output based on the parameters being selected (checked) so if M1+M2 is selected, I should get a string output something like m1_m2.

    Also I created the pcell using "Conditional inclusion" in Pcell plugin.

    I will look into the use of rodNameShape() and rodNameObject()
