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

  • I too am confused about what is being done here. It seems to me that you should be recording this information when you create the instances. You said that you are creating the pattern with a skill script. I interpret that to mean that you have a skill script that places the instances using dbCreateInst. If that is true, then, like Andrew said, you would have the instance id after you create each inst (x = dbCreateInst...). If so, then you could change the instance name to contain information about where the instance is in the pattern:
    x~>name = "Inst_1_3"
    sprintf(instName "Inst_%d_%d" row col)
    lowerLeft = dbFindAnyInstByName(geGetEditCellView instName)

    Or you could put properties on the instance:
    x~>R =1
    x~>C = 1
    lowerLeft = setof(x geGetEditCellView()~>instances x~>R==0 && x~>C==0)

    Or you could create a table that contains your information:
    myTable = makeTable("myTable" nil)
    myTable["lowerleft"] = x ; Where x is the return value from dbCreateInst.
    or
    myTable[0:0] = x

    If you are looking at a cellview that already has the instances in it, then I think you have to do what Andrew suggested in his first response.
