WebSep 15, 2024 · Hold timing violations can mainly occur due to less delay in the data path. There can be multiple reasons for this let us discuss them one-by-one. Some combinational paths have very few logic cells. In this case, the data transfer takes place at a very high speed. This creates the hold timing violations.
