Modelsim-10仿真教程是一份针对初学者设计的详细且易于理解的指南,它主要讲解如何在Quartus软件环境中有效地利用Modelsim进行电路仿真。本教程首先强调了安装Modelsim SE 10.1和Quartus II 10.1版本的重要性,这两个工具在硬件描述语言(HDL)如Verilog或VHDL的仿真过程中起着关键作用。 在开始仿真之前,用户需要配置Modelsim以使用Quartus提供的仿真库,因为Quartus本身并不支持独立的测试台(Testbench)。加入Altera库的原因包括对特定功能模块的支持,如megafunction和lpm库,以及进行精确时序仿真。Modelsim与Quartus库的集成需要通过以下步骤: 1. 设置仿真库路径:在Modelsim的安装目录下创建一个名为"altera"的文件夹,然后将Quartus自带的仿真库文件复制至此。Modelsim默认的工作目录是"work",这里存放的是当前工程下所有被编译的设计单元。 2. 新建库:Quartus提供的库文件通常有.v和.vhd格式,用户需根据使用的编程语言(Verilog或VHDL)选择相应的库文件。常用的库文件有220model.v、220model.vhd等,但并非所有文件都需要编译,尤其是单一语言项目。以altera_mf.v为例,用户可以学习如何创建预编译库,这有助于减少不必要的编译过程。 3. 针对只使用Verilog的情况,建议根据实际需求选择性地编译所需库,避免冗余。这一步骤有助于提高仿真效率和准确性。 4. 在Modelsim中,库可以分为两类:工作库(working)和其他库。工作库是默认选项,包含了当前工程中的设计元素。理解并管理这些库对于仿真项目的顺利进行至关重要。 这篇教程深入浅出地介绍了如何在Modelsim中集成Quartus库进行高效、准确的电路仿真,无论是初次接触Modelsim的开发者还是有一定经验的用户,都能从中获益匪浅。通过这个教程,学习者将掌握如何设置环境、管理库文件,并进行有效的代码调试,从而提升他们的硬件验证能力。

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).
