WebJan 23, 2013 · Solution. If the Hold Time Violation is associated with an OFFSET IN constraint, the data path is faster than the clock path. Either increase the delay associated with the data path or decrease the delay associated with the clock path. To decrease the clock path delay, verify that the design is using the global clocking resources. You can …

WebBaselining is a process in which you create the simplest timing constraints and initially ignore I/O timing. Then, carefully add the timing exceptions/constraints needed to achieve timing closure.

WebMar 2, 2024 · Though Static Timing Analysis (STA) is much better because it analyzes all paths, GL simulation also serves as a backup to check for hold and setup time violations (chip designers must be paranoid!) We use Synopsys Design Compiler (DC) to synthesize our design, which means to transform the Verilog RTL model into a Verilog gate-level …
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. WebDec 12, 2014 · I was running timing simulation using NCSim and due some issues the SDF annotation failed. However, I did not receive any timing violation as It happened before while using modelsim. Receiving violations is a sign that there are delay information. The delay info exists in the library models I compiled.
