To guarantee that an application-specific integrated circuit (ASIC) meets its timing requirement, at-speed scan testing becomes an indispensable procedure for verifying the performance of ASIC. However, at-speed scan test suffers the test-induced yield loss. Because the switching-activity in test mode is much higher than that in normal mode, the switching-induced large current drawn causes severe...
The voltage-/temperature-induced delay estimation error of conventional logical effort is much more severe in near/sub-threshold region. In this paper, super-/near-/sub-threshold logical effort models are proposed to eliminate delay estimation error caused by voltage and temperature variations. These models establish over the four different nanoscale CMOS generations. They also take environmental...

Given a circuit netlist, based on the slack analysis in the netlist, the optimal voltage in a maximum slack-sharing cluster(MSC) can be obtained to maintain the performance of the netlist. Furthermore, according to the optimal voltages of all the MSCs and the constraints for multiple-voltage assignment, an efficient assignment approach is proposed to assign multiple voltages onto the given circuit...
