Abstract :
A flexible test architecture for embedded cores and all interconnects in a system-on chip (SOC) is presented. It targets core testing parallelism and reduced test application time by using, as much as possible, existing core interconnects to form TAM paths. It also provides for dynamic wrapper reconfiguration. Algorithms that minimize the use of extra interconnects for the TAM path formation are presented and evaluated.
