"Webb4 aug. 2024 · Using delays in test bench design. This is one reason why I avoid the “#” syntax in Verilog, such as a <= #2 b;. Just because you tell the Verilog simulator that something will happen “2.5ns” later, doesn’t mean it will achieve that “2.5ns” result in hardware. Worse, these statements are often ignored by the synthesizer. " - Run post-synthesis functional simulation

Webb5 apr. 2024 · In short the post-implementation, or timing simulation takes into account the delays associated with the actual synthesis and logic placement. It is a more accurate picture of how robust your design is. While the behavioral simulation has to account for clocked delays like registers it is naive about routing delays.
