Designing for scan test of high performance embedded memories
E. Kofi Vida-Torku, G. Joos · 2002
The addressing and clocking schemes in PowerPC/sup TM/ microprocessor embedded memories present modeling challenges. The ability of most scan based test tools to accurately generate test patterns for these embedded memories is limited. What is needed is aggressive Design for Test implementations that can help the test generation tools. In this paper we present our experiences in the design, modeling, and test of high performance embedded memories on the PowerPC microprocessors.
