Abstract
An integrated-circuit chip comprises a plurality of scan flip-flops and a retention cell. The chip is configured to have a scan-capture mode, in which the plurality of scan flip-flops and the retention cell are connected to respective functional circuitry of the integrated-circuit chip, and to have a scan-shift mode, in which the plurality of scan flip-flops and the retention cell are connected so as to form a scan chain for use during scan-chain testing of the integrated-circuit chip. The chip further comprises on-chip test circuitry arranged to generate and output a save signal, a clock signal, and a restore signal to the retention cell, for testing the retention cell during scan-chain testing of the integrated-circuit chip.
