QuestaSim help

I have just started working with QuestaSim. Before that i was working with modelsim. Is there anybody know what feature QuestaSim has that modelsim doesn't have? I mean in case of systemVerilog and verification

这个和modelsim有什么区别

you can study it from it's example files.

The example is under the setup directory.

modelsim for fpga and sample asic testing/verification, questasim for asic and fpga verification;
questasim has some new features than modelsim, for example : uvm/ovm/vmm verification methodology, verification manage tools, low power verification tools and better performance. if your projection is some bit big, I suggest you to use questasim for your work.
