Interview Question: Impact of Dummy Fill on Timing
How can you quantify the impact of dummy fill on post-layout timing? Dummy fill can be inserted into a layout using SOC Encounter or post-tape-out tools like Calibre/Assura. You should then extract dummy fill using Fire-n-Ice extractor and compare pre-fill and post-fill timing. Can you compare the impact of filling approaches (grounded vs. floating)?
