There are two bench testing directories, one for Verilator sources, and one for C++ simulation sources that will work with Verilator. The Verilog sources may or may not be used with Verilator. Indeed, they would work nicely as stand--alone top--level files that may be used to test whether or not the UART on a given board works.
