There are 2 repositories under verilog-testbenches topic.
iverilog extension for Visual Studio Code to satisfy the needs for an easy testbench runner. Includes builtin GTKWave support.
This example .BMP generator and ASCII script file reader can be adapted to test code such as pixel drawing algorithms, picture filters, and make use of a source ascii file to drive the inputs of your .sv DUT module while offering logging of the results, and executing the list of commands in order.
High speed C/C++ based behavioural Verilog memory model
This project was a nice idea I had to build a digital logic clock on the DE1-SOC FPGA, while practicing System-verilog, Asynchronous design, and advanced debugging techniques
