Modelsim Lattice Edition: What are the limitations of Modelsim Lattice Edition compared to Modelsim PE?

1. Component instance count is limited to 5000. Watermarked components do not count against this limit.

  • Watermarked components have an indicator and these includes components from all the simulation libraries and primitives. If the pre-compiled watermarked libraries are used, these won’t count towards the 5000 instances limit. If the limit exceeded, Modelsim will become slower.
  • Simulation Libraries can be found under <Diamond>/cae_library/simulation/Verilog; <Radiant>/cae_library/simulation/Verilog.
  • Pre-compiled Libraries can be found under <Diamond>/modeltech/lib ; <Radiant>/modeltech/lib.

2. 60% performance of ModelSim PE

3. No DPI or FVI

4. No Dataflow view
