Description

This IP-core implements a memory tester for memories connected over AXI. It writes patterns, reads them back and checks whether there are no errors.

Simulations and Testbenches

A regression test script for Modelsim is present. To run the regression test, execute the following command in modelsim from within the directory sim

source ./run.tcl
