Abstract :
The boundary scan (BS) technique offers a convenient alternative to physical probing. This paper presents new boundary scan architecture for Built-In Self-Test (BIST). The Boundary Scan Register (BSR) input cells have been configured to operate as a Test Pattern Generator (TPG) in the BIST mode. The BSR output cells have been configured to operate as a Multi-Input Shift Register (MISR) In the BIST mode. The Test Access Port Controller (TAPC) controls the BIST process. Instructions for BIST process are proposed. This configuration supports the BIST for both the Built-In Logic Block Observer (BILBO) register and the register transfer level. This design Implemented on the Field Programmable Gate Array (FPGA) Spartan X2C200 family.
