METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR IMPLEMENTING SCAN-CHAIN-SPECIFIC CONTROL SIGNALS AS PART OF A SCAN CHAIN |
摘要 |
A method, apparatus and computer program product are provided for implementing scan-chain-specific control signals as an integral part of a scan chain. A scan input vector including scan data input and a scan control signal is applied to a register latch that forms the scan chain. The register latch includes a logic gate for combining a global clock control (THOLD) signal and the scan control signal. The scan control signal is routed around the register latch and including in a scan output vector including scan data output. Chain-specific control signals are eliminated from a clock control signal distribution tree used with the scan chain of the invention.
