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...
In this paper a hold-friendly scan flip-flop is introduced whose scan pin hold characteristic has improved while data pin timing and power are left intact. This characteristic helps to resolve scan chain hold problem while meeting the maximum frequency in data path. This solution can reduce the number of buffers inserted in the scan chain to fix hold violations. The new flip-flop can save up to 27%...
