Interact with your instruments The ScanWorks Internal JTAG (IJTAG) tools allow system-on-a-chip (SoC) designers, DFT engineers and validation engineers a new and simpler way to access, control and run any embedded instrument designed into chips. When the IEEE ratifies the IEEE 1687 IJTAG standard in 2013, it will enable easy access to run any functional type of IJTAG instrument. ASSET is the first tool supplier with development tools available today for the early adopters of this important new technology. Once instruments are connected to the on-chip IJTAG network, ScanWorks reads the IJTAG standard’s Interconnect Connectivity Language (ICL) and automatically knows where all the instruments in the chip are. Then ScanWorks uses the IJTAG standard’s other language, Procedural Description Language (PDL), to run the embedded instruments that have been selected to solve the problem at hand. Currently, tools to control embedded instruments, if they exist at all, are usually proprietary to a certain technology. As a result, the engineer would need multiple tools and multiple access mechanisms, or he would have to develop his own tools. The IJTAG standard and ScanWorks IJTAG chip test and debug tools solve this mess.
