Integrated Circuits, Printed Circuits Boards, and Multi-board systems are becoming increasingly complex to test. A major obstacle is test access, which would be eased by effective standards for the communication between devices-under-test (DUTs) and the test manager. Currently, the Internal Joint Test Access Group (IJTAG) work at micro-level on a standard for interfacing embedded on-chip instruments while the System JTAG (SJTAG) work at macro-level on a standard for system-level test management that connects IJTAG compatible instruments with the system test manager. In this paper we discuss requirements on a test protocol to be used in an SJTAG/IJTAG environment. We have from a number of use scenarios made an analysis and defined protocol requirements. We have taken the Standard Test and Programming Language (STAPL), which is built around a player (interpreter), and defined required extensions. The extensions have been implemented in an extended version of STAPL and we have made experiments with a PC acting as test controller and an FPGA being the DUT.
