Abstract

This paper presents novel control schemes for testing embedded cores in a system on a chip (SOC). It converts a traditional BIST scheme into an externally controllable scheme to achieve a high test quality within optimal test execution time without inserting test points. The scheme promotes design and test reuse without revealing IP information.
