This post describes how to code a technology-independent SystemVerilog ROM memory with parameters to set the data width and memory depth (i.e. number of locations) and the use of an external file for setting the initial contents....

The clocking block provides a means of specifying the timing of synchronous signals relative to their clock. It defines the timing that the testbench will use to sample outputs from the DUT and drive inputs towards the DUT...

There are many different ways of creating state machines, this article will describe how I tackle them using SystemVerilog and the automatic state encoding feature of Vivado synthesis...
