A PLL based at-speed functional testing concept, which eliminates the need for a tester-driven high-speed clock interface is presented. Jitter tolerance circuits have been implemented to provide immunity to clock jitter. The concept was verified on a 100 square mm silicon device built in 0.18 micron technology above 200 MHz speed. Simulation results show that the concept can be extended to higher speeds.
