This document discusses limitations of traditional serial scan design for testing integrated circuits and proposes an alternative called Random Access Scan (RAS). RAS addresses three key limitations of serial scan: 1) test data volume, 2) test application time, and 3) test power. In RAS, flip-flops act as addressable memory elements during test mode, reducing time to set and observe flip-flop states compared to serial scan. While RAS requires more gates and test pins than serial scan, it significantly reduces switching activity and power consumption during testing.
