Extended STAPL as SJTAG Engine
Integrated Circuits (ICs) and multi board systems are becoming increasingly complex to test. A key to successful testing is effective standards. Currently, at micro level the Internal JTAG (IJTAG) focuses on the development of a standard for embedded on chip instruments while at macro level the System JTAG (SJTAG) works on defining a standard for system level test management; mainly connecting the IJTAG standard with the system test manager. In this paper we discuss language requirement for making and handling access between the test manager and embedded instruments. As a base line we make use of the Standard Test and Programming Language (STAPL) We have identified a number of required extensions that we have implemented in an extended STAPL+ player (interpreter) and language. We have performed initial experiments where we simulated an embedded environment with a PC as test controller running the new player and an FPGA serving as device under test.
