Ho to find top level connectivity for instances using SKILL in Layout

Miguel V

Hi,

I have a set of bondpads and I am trying to write a SKILL function that will display the coordinates and top level connectivity for each bondpad.  For example, I have pads labeled PWR, PWRres, GND and clk at the top level. I want the function to output something like this:  bondpad   (x,y)     PWR

I got the coordinates to display properly but still having troubling pulling the net associated with each bondpad.  I've searched quite a bit on here and other sources but I'm currently stumped.  Any ideas on how to approach this or are there other properties associated with cv~>instances that I am missing?  I've tried using inst~>conns~>net~>name but all I get are the connections at the cell level which end up being "IO" or "sub"

Thanks

  • Hi Miguel,

    I understand your feeling now. Sorry for that. May be if you had given more description on your requirement some one would have pointed you this. Sometimes we try to build a world with our little knowledge of SKILL and finally get embarrassed with an already available tool. But nothing goes waste I bet you might have sharpened your SKILL scripting when you try to reinvent the wheel.
