Buffer design for reducing Hold violations & IR drop (Feb. 17, 2015)
In shrinking technologies, all SoC’s have to work in multi modes and multi corners. So there is a tough challenge to meet setup and hold in all corners. Hold violation closure for a design involves Non-Si Hold closure (due to clock - skew) & Si Hold closure (due to clock and data noise). Non-Si Hold fixing is done by downsizing the existing logic or by putting more hold buffers in the path (primarily of Low drive buffers) while the Si-Hold fixing can be done by adding more buffers.
