Setup an open source verilog simulator on windows
Icarus verilog is free and light weight simulator to execute the simple code for verilog.
Step 1: Download and install essential soft-wares
1) Download and install the Icarus verilog version "iverilog-0.9.7_setup" from link provided here.http://bleyer.org/icarus/
2) Download and install the GTKwave from link provided here.
https://sourceforge.net/projects/gtkwave/files/
3) To edit the code we will require the notepad++. So, download and install from the link provided here. https://notepad-plus-plus.org/downloads/
Step 2: Setting up path for Iverilog and GTK wave to use them as a command from command prompt
Goto My computer -> right click on the screen -> select the properties -> from control panel home -> select advanced system settings
OR
Directly go to search the option and enter the word environment -> select the second option edit the system environment variables
1) select environment variable
2) Go to system variables-> paths-> edit
3) Set the path of both Iverilog and GTKwave into path. Separate each path by placing first ";" than entire path location mention as below.
i.e. first ; and then path C:\Program Files (x86)\iverilog\bin next again put ; and C:\Program Files (x86)\gtkwave\bin
