ESCAPE: Elegant Scan Chain Activity Probability Establishment for Programmable Low-Power LBIST
DescriptionThis paper presents an Elegant Scan Chain Activity Probability Establishment (ESCAPE) architecture for programmable low power LBIST. In the designed low-power control circuit, a programmable probability generator periodically outputs a user-configurable sequence of probabilities to drive hold registers. A 2D AND-gate array formed by two groups of hold registers then produces a rich set of low-power control signals. By modulating the enable probability of the lockups situated before the phase shifter, ESCAPE achieves precise per-chain power management. Experimental results on industrial-scale designs demonstrate that, the proposed method achieves high coverage, while reducing peak power consumption and incurring lower hardware overhead.
