Fixing setup and hold violations
WebNov 15, 2024 · It can be used to fix both setup and hold violations. Let’s explain with the help of a simple example: In the above circuit, for the simplification let’s take the skew value to be zero. Due to the large value of Tcombo1, there is a setup violation of 2ps. Due to a small value of Tcombo2, the setup slack is +4ps but the hold is violating by 1ps. WebFollowing strategies can be useful in reducing the magnitude of hold violation and bringing the hold slack towards a positive value: 1. Insert delay elements: This is the simplest we can do, if we are to decrease the magnitude of a hold time violation. The increase in data …
