WebModelSim User - Microsemi WebThis chapter discusses ModelSim’s implementation of SDF (Standard Delay Format) timing annotation. Included are sections on VITAL SDF and Verilog SDF, plus troubleshooting. Verilog and VHDL VITAL timing data can be annotated from SDF files by using the simulator’s built-in SDF annotator. ASIC and FPGA vendors usually provide tools that ...

If you use the “list of port declarations” syntax, you need to completely describe the port.

Web16 Dec 2013 · Setup Analysis (Max Delay Analysis) Now, let us see what is meant by setup analysis for a timing path. Timing paths can be the following types: 1. Input port to a D pin of Flop. 2. CLK pin of Flop1 to D pin of Flop2 3. Q pin of flop to an output port 4. Input to output port through purely combinational logic.
