Questa-Intel FPGA Starter Edition (ModelSim) But they all look and feel the same, and they are sufficient, even for advanced VHDL projects. That’s why you will find many installation options for ModelSim on this list.Īll free ModelSim versions are speed-restricted in some way. ModelSim / QuestaSim, produced by Siemens EDA (formerly Mentor Graphics), is one of the most popular HDL simulators. I recommend installing another operating system in a virtual machine to get around the problem. Mac OS is the most challenging platform because there’s only one open-source simulator that works natively. But with a little effort, you can make it work in other distros, including Ubuntu. FPGA vendors usually only support the Red Hat Linux distribution. Microsoft Windows is the easiest to install on, but many simulators also have a Linux version. But fortunately, there are many free and legal alternatives that you can download and install. This is the complete offline setup of Mentor Graphics ModelSim SE 10 and compatible with all latest operating systems.Professional VHDL simulators are more expensive than most individuals can afford.

Native support of Verilog, SystemVerilog for design, VHDL, and SystemC.Features of Mentor Graphics ModelSim SE 10.5 Free It delivers dramatic throughout improvements of up to 3X when running a large suite of test cases.


The b-box helps the designers in compiling of non-changing elements and optimizing once and reused when running a modified version of the testbench. It also supports very fast time-to-next-simulation turnarounds while maintaining high performance with its new black box use model, known as b-box. Gate-level performance can also be increased by up to 4X and capacity by over 2X with the help of vopt mode. With the help of vopt performance mode, engineers can improve Verilog and mixed VHDL/Verilog RTL simulation performance by up to 10X.
