QuestaSim 10.7c excels at mixing VHDL-2008 with Verilog/SystemVerilog. The foreign language interface (FLI) and Verilog Procedural Interface (VPI) are highly optimized. This is crucial for legacy military designs where VHDL handles the control logic and Verilog handles the high-speed DSP blocks. The foreign language interface (FLI) and Verilog Procedural
