MarciaTesta: An Automatic Generator of Test Programs for Microprocessors' Data Caches

摘要

SBST (Software Based Self-Testing) is an effective solution for in-system testing of SoCs without any additional hardware requirement. SBST is particularly suited for embedded blocks with limited accessibility, such as cache memories. Several methodologies have been proposed to properly adapt existing March algorithms to test cache memories. Unfortunately they all leave the test engineers the task of manually coding them into the specific Instruction Set Architecture (ISA) of the target microprocessor. We propose an EDA tool for the automatic generation of assembly cache test program for a specific architecture.
