Wide voltage range circuit has got widespread attention where in-situ timing monitoring based adaptive voltage scaling (AVS) becomes necessary to reduce the design margin. However, the severe PVT variations across near-threshold to super-threshold cause too many critical paths to be monitored. Here activation oriented monitoring paths selection method is proposed to reduce the monitored paths for wide voltage IC. The minimum delay value of the longest activated path is found by dynamic timing analysis and set as the selection threshold. Those paths longer than this threshold by STA analysis are selected to be monitored. Applied on a 40 nm AVS Systemon-Chip, it reduces the monitoring paths to only 22% of all critical paths with remarkable power gains under 0.6 V–1.1 V.
