Making a VGA Driver in SystemVerilog

The author, Lukas Werner, wrote a blog post on their website about creating a VGA driver in SystemVerilog, a hardware description language. They started by explaining the basics of the VGA interface, including the 640x480 resolution, 25 Hz refresh rate, and 256 colors. They then described the process of designing the VGA driver, including the creation of a clock domain crossing, a state machine, and a pixel pipeline. The author also discussed the challenges they faced while designing the driver, such as handling the VGA's timing requirements and dealing with the 25 Hz refresh rate. They provided a link to the source code on GitHub, which includes a SystemVerilog module for the VGA driver and a testbench to verify its functionality.
