FLEXIBLE PERFORMANCE SCREEN RING OSCILLATOR WITHIN A SCAN CHAIN |
摘要 |
Aspects of the invention provide for a flexible performance screen ring oscillator (PSRO) integrated within a scan chain. In one embodiment, a circuit structure to create the flexible PSRO includes: a plurality of programmable scan chain elements; and a forward test scan chain path through the plurality of scan chain elements; wherein each of the programmable scan chain elements includes additional circuitry for a backward path, such that the backward path and the forward test scan chain path are combined to create the PSRO. |
