SYSTEM SCAN PATH ARCHITECTURE |
摘要 |
A system scan path architecture is provided by a device select module (DSM) (18) which may be used in conjunction with associated circuits (16a-b) to select secondary scan paths (PATH1-m) on each circuit for coupling with a primary scan path on a test bus (14). The test bus (14) is controlled by a primary bus master (12). Remote bus masters may be used in conjunction with the DSMs (18) to provide serial-scan testing independent of the primary bus master (12). |
