Document Table of Contents Post-Fit Simulation Files

Post-fit simulation is the simulation of the netlist generated from the original RTL design after it has been mapped, synthesized, and fit. The netlist represents the actual hardware and its connections as they appear in the FPGA. Intel® Quartus® Prime generates the netlist and can generate a Standard Delay Format (.sdf) file with the timing information for all connections. The simulation can be functional only (without the timing information) where all wires and gates take zero time, or it can be a timing simulation where the time for all transitions is based on the SDF information.

Post-fit simulation can serve a number of different purposes:
  • Used to perform a dynamic verification of the timing of the design.
  • Used to verify the functional correctness of either the design, the compilation flow (in particular, the fitter), or both.
