?How to display timing slacks for all path going through a specific cell instance?

lionelriviere

I am looking for a way to visualize the timing slack for all paths going through a specific cell. The intent is to understand why the cell is placed close/far from a specific launch/capture flop ? 

Any recommendation ? 

  • You can use Global Timing Debug to create a category of the paths going through that instance. Then you can click the check box next to each path to have it displayed in the GUI. If you're not familiar with GTD there is a good RAK here (8th one in the list):

    Hope this helps,
