Verilog Practices

This site explains the various concepts like divide by n clocks, FIFO, I2C etc. The blog provides the concepts, then the Verilog code and explanation. Finally, the simulation of the code and waveform. The blog also provides simple test cases to run and test the Verilog code.

The synthesis and the simulation are done by the open-source tools. The installation of the tool is also given in detail as blog posts.
