test_values.txt will contain all details about every single generated test, for debugging. ram_content.txt is the file that will be read by Vivado to load the ram values

How to import in Vivado

You can directly import the gen_testbench_reset.vhd (or gen_testbench_no_reset.vhd) file as source in Vivado, then modify this file to match the folder containing the generated ram files. Instruction on how to modify it are included in the .vhd file itself.
