Decap Cells

IR drop analysis in VLSI explained for physical design engineers: where supply and ground drop come from, static vs dynamic IR drop, vectorless and vector-based analysis, how IR drop affects setup and hold, and how to debug and fix hotspots, with illustrative examples, a flowchart and interview Q&As.

Decap Cells Decap cell is basically a capacitor cell which is used temporarily in the design between power and ground rails to counter the functional failure. We cant have functional failure in our design. So to avoid any kind of functional failure due to Dynamic IR, we use Decap cells in our design.  Current (I) […]
