Manufacturer:INFINEON Description:ADDRESSING SCHEME - The BRT12H architecture extends the functionality of the IEEE 1149.1 Standard by supplementing that protocol with an addressing scheme which allows a test controller to communicate with specific STA111s within a network of STA111s. That network can include both multi-drop and hierarchical connectivity. In ef- fect, the STA111 architecture allows a test controller to dynamically select specific portions of such a network for participation in scan operations. This allows a complex sys- tem to be partitioned into smaller blocks for testing purposes. The STA111 provides two levels of test-network partitioning capability. First, a test controller can select individual STA111s, specific sets of STA111s (multi-cast groups), or all STA111s (broadcast). This STA111-selection process is supported by a Level-1 communication protocol. Second, within each selected STA111, a test controller can select one or more of the chips three local scan-ports. That is, individual local ports can be selected for inclusion in the (single) scan-chain which a STA111 presents to the test controller. This mechanism allows a controller to select spe- cific terminal scan-chains within the overall scan network. The port-selection process is supported by a Level-2 proto- col. HIERARCHICAL SUPPORT - Multiple BRT12Hs can be used to assemble a hierarchical boundary-scan tree. In such a configuration, the system tester can configure the local ports of a set of STA111s so as to connect a specific |
