Which Verilog Simulator to Install

[MJ96]

I'm new to FPGAs and Verilog simulation tools. I'm building a simple processor for fun and would like to know which Verilog simulation would be best for me to install. I would like that there be no code size limit. I'm willing to pay for it, but not thousands of dollars. BTW, I'm a college student if that helps.

Both of these are free and good simulators for verilog code:

https://github.com/verilator/verilator

https://github.com/steveicarus/iverilog

I use icarus verilog to simulate all my Altera FPGA designs written in verilog and find that is is accurate and fast.

They are both also very general purpose for simulating arbitrary verilog code, not necessarily FPGA related.

And for a waveform viewer, GTKwave is also an excellent free choice: https://gtkwave.sourceforge.net/

Kindly note that there will be some slowness on the first reply due to the public holiday, we will get back to you as soon as possible.

Thumb up for the Verilator and the Icarus Verilog.

Add on: there is also the free Aldec's VHDL Student Edition that you can check it out.
