ModelSim是一款广泛应用于硬件描述语言(HDL)仿真领域的流行工具,由Mentor Graphics公司提供。本教程旨在帮助用户入门并熟悉ModelSim的基本操作流程。以下是详细的步骤和关键知识点: 1. **准备工作**:首先,确保将ModelSim自带的教程文件复制到一个新目录(如D:\modelsim_test),并将C:\Modeltech_6.0\examples\projects\verilog下的内容也一并拷贝。 2. **启动ModelSim**:双击启动ModelSim,确保计算机已连接网络,因为某些功能可能依赖于网络。 3. **创建工程**:在ModelSim界面中,通过File->New->Project创建一个新的工程,命名为counter_test,用于存放模拟项目的所有文件。 4. **添加文件**:将待模拟的源文件(如tcounter.v和counter.v)加入到工程中,便于管理和编译。 5. **编译与模拟**:通过Library页面选择work库和test_counter,执行编译操作(通常点击run图标或在控制台输入run命令)。之后可以选择模拟时间,例如run100ms。 6. **观察波形**:使用View->Signals功能监视波形,高亮dutcounter项后,添加需要监视的信号至Wave视图。可以通过右键菜单进一步操作,如更改信号显示方式。 7. **命令行操作**:ModelSim的命令行是高效工作的利器,如设置工作目录(changedirectory...)或在属性中修改起始位置以避免频繁调整。掌握基本命令行操作有助于提高效率。 8. **放大与局部查看**:利用ZoomMode图标可以放大波形局部区域,便于精确分析。 9. **版本差异**:注意ModelSim有不同的版本,如SE版为全功能,可能包含更多特性。 10. **注意事项**:学习过程中,不仅要熟悉图形界面,还要了解命令行操作,因为有些高级功能可能不能通过菜单和工具栏直接实现。 通过这个ModelSim基础教程,用户可以逐步掌握如何创建、编译、调试和分析Verilog代码,为HDL设计验证提供有力支持。继续深入学习,可以探索更复杂的仿真设置和高级分析技巧,提升硬件设计和验证能力。

Mentor, a Siemens business, has unveiled ModelSim 10.7, is unified debug and simulation environment gives today's FPGA designers advanced capabilities in a productive work environment. About Mentor Graphics ModelSim. Modelsim HDL simulator provides FPGA customers with and easy cost-effective way to speed up FPGA development, lab bring up and test. Many FPGA designers go to the lab before adequately vetting their design. This means weeks or even months of inefficient debugging time in the lab. Testing in the lab has limited visibility of the signals in design. It can take 8 hours to do a place and route just instrument additional signals or make a small bug fix. With simulation the debug loop is much faster and there is complete visibility into the signals in the design. Simulation enables a much higher quality FPGA design before entering the lab allowing time spent during lab debug much more productive and focused. In addition to supporting standard HDLs, ModelSim increases design quality and debug productivity. ModelSim’s award-winning Single Kernel Simulator (SKS) technology enables transparent mixing of VHDL and Verilog in one design. Its architecture allows platform-independent compile with the outstanding performance of native compiled code. The graphical user interface is powerful, consistent, and intuitive. All windows update automatically following activity in any other window. For example, selecting a design region in the Structure window automatically updates the Source, Signals, Process, and Variables windows. You can edit, recompile, and re-simulate without leaving the ModelSim environment. All user interface operations can be scripted and simulations can run in batch or interactive modes. ModelSim simulates behavioral, RTL, and gate-level code, including VHDL VITAL and Verilog gate libraries, with timing provided by the Standard Delay Format (SDF).
