Abstract: Circuit design computing equipment may perform depopulation operations, constraint generation, and repopulation operations in a circuit design in anticipation of register retiming operations. A depopulation operation before placement and/or before routing operations may prevent the respective placement and/or routing operations from placing and/or routing registers from the circuit design. Constraint generation may create constraints for placement and/or routing operations that allow for the reinsertion of registers after routing operations. Repopulation operations may reinsert registers in the circuit design after routing operations according to the constraints. If desired, the circuit design computing equipment may perform register retiming operations to further improve the performance of the circuit design.

The first circuit symbol has a plurality of first pins having a first position vector associated therewith. The second circuit symbol has a plurality of second pins having a second position vector associated therewith, and each of the plurality of second pins corresponds to a respective one of the plurality of first pins.

Abstract: A critical-path timing sensor detects set-up timing failures from a functional critical path to a path flip-flop. The functional critical path carries test data during test mode, and normal data during normal device operation. The path flip-flop's D input and Q output are compared by an exclusive-OR (XOR) gate and sampled by an early capture flip-flop that is clocked by a delayed clock, sampling D and Q just after the path flip-flop is clocked. When set-up time fails, D and Q differ just after the clock edge and a timing failure is latched. Timing failures activate a controller to increase VDD, while VDD is reduced in the absence of timing failures. Process variations are accounted for, allowing for lower power or faster operation. A margin delay between the functional critical path end and the early capture flip-flop detects timing failures before they occur in the path flip-flop.
