getting the dbID for an instance in the layout

Inas Mohammed

Hello,

I need to get the dbID for certain transistor in order to do some operations on it after that.

The idea is that i need to check for a transistor in a pattern, if this transistor is at lower left of upper right do some commands.

so i need to get value of x which then will be used as follows.

when(row=0 && col==0  lowerleft=x)

when(row=Rows-1 && col=Cols-1 upperright=x)

I thought about like trying to create instances again on the old one with the same names in these places using dbCreateInst just to have the ID, then use it.

But it doesn't work

So can you help me with this issue please.

thanks

  • yes i generated the pattern via skill script. And i mention above that i tried to use the "dbCreateInst" but i didn't know how to use it for this purpose which is getting the IDs. I found an instance created instead which is not what i want.
    What i was doing is like the following with an inner loop for filling the columns of the row mentioned in an outer loop:
    masterID=dbOpenCellViewByType(lib cellname cellview)
    x=dbCreateInst(cellView masterID name 1 list(x y) "R0")

    name--> is a variable mention earlier in the code.

    But the lines i wrote didn't work correctly. I need to know how can i use this function to return the IDs of the instances.
    Can you give me an example for this usage of this function, please?
