It's now called QuestaSim I believe. But are you sure it can't handle simulating large designs? If yes, what is the full-featured software from Mentor that can?
> Heck, maybe they can drive adoption of one of the up-and-coming HDL's like chisel
Chisel isn't a full-blown HDL from what I understand; it's only a DSL that compiles to Verilog. In other words, you'd still need a Verilog simulator to actually run your design.
Questa is the full blown tool. Modelsim is a step down and that's what comes with FPGA tools. Usually the version of modelsim that Xilinx and Altera ship is crippled performance wise.
