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...
The paper presents a new unifying formalism introduced to effectively support the automatic generation of assembly test programs to be used as SBST (Software Based Self-Testing) for both data and instruction cache memories. In particular, the new formalism allows the description of the target memory, of the selected March Test algorithm, and the way this has to be customize to adapt it to the selected...
