Abstract
A signal delay cell for use in resolving hold time violations in an IC has a first multiplexer having a first functional data input node and a scan data input node TI and a second multiplexer having a second functional data input node, a second input node connected to the output of the first multiplexer and a flip-flop module. The propagation of a data input signal applied to the first multiplexer is delayed, and the hold margin of the flip-flop module is increased by transit through the first multiplexer. The signal delay cell is available to replace a flip-flop having a scan data hold problem, and also for use in solving a functional data violation in the same or another cell.
