In order to validate the verilog ram memory implementation we will implement a model in verilog test-bench to generate the controls. The way we are going to model it is as follows.
First we are going to fill in the memory with write only commands. The data we are going to write will be random. After filling in the memory, we will enable reads. During reads we will request random addresses between 0 and 63. We will dump both read and write data in text files. Links to test-bench, write data/memory contents, read data and analysis.
