说明：  Mentor公司的ModelSim是业界最优秀的HDL语言仿真软件，它能提供友好的仿真环境，是业界唯一的单内核支持VHDL和Verilog混合仿真的仿真器。它采用直接优化的编译技术、Tcl/Tk技术、和单一内核仿真技术，编译仿真速度快，编译的代码与平台无关，便于保护IP核，个性化的图形界面和用户接口，为用户加快调错提供强有力的手段，是FPGA/ASIC设计的首选仿真软件。
(Mentor's ModelSim, the industry's best HDL language simulation software, offers a friendly simulation environment and is the industry's only single-core simulator supporting VHDL and Verilog mixed simulations. It uses direct optimization of the compiler technology, Tcl / Tk technology, and a single kernel simulation technology, compile and emulate fast, compiled code has nothing to do with the platform, easy to protect IP core, personalized graphical interface and user interface to speed up the user to debug wrong Provide a powerful means of choice for FPGA / ASIC design simulation software.)
