Are Cadence NC-Sim and Xcelium supported in Diamond?

For simulation, Lattice supports Cadence NC-Sim. Please see the additional notes below.

Simulation libraries follow the Verilog/VHDL LRM, so moving from older to newer simulators should not be an issue. Moving from newer to older simulators may cause issues if new language constructs are used. Our simulation libraries for Diamond have not changed in many years.

For Xcelium, there is a plan to support it in the next major release of Diamond.
