Achieving desired synchronization at sequential elements while testing integrated circuits using sequential scan techniques

A programmable delay circuit is provided in either data input path or a clock input path of a sequential element contained in a scan chain of an integrated circuit. The scan chain is used to test the integrated circuit using a sequential scan technique (e.g., Automatic test pattern generation (ATPG)). Due to the programmability of delay magnitude, the burden on a designer to achieve synchronization of the data input with the clock signal while testing, is reduced.
