ModelSim simulates behavioral, RTL, and gate-level code - delivering increased design quality and debug productivity with platform-independent compile. Single Kernel Simulator technology enables transparent mixing of VHDL and Verilog in one design.



FormalPro uses static formal verification techniques to prove that a design is functionally identical to its golden reference. This is orders of magnitude faster than traditional gate-level simulation—designs that take days or weeks can be verified in hours or even minutes using FormalPro.
