EUROASIC'92:

A board-level BIST architecture for boards loaded with ASICs and VLSI components, compliant with the IEEE 1149.1 BST standard, is described. This BIST architecture consists of a test processor core, with an optimised architecture for controlling the board-level BST infrastructure, an optional system-level testability bus interface, to be included when a system-level test strategy is to be implemented, and a ROM containing the test program, which is automatically generated by an ATPG tool.
