JTAG Technologies

We are boundary scan.


While many ICs are equipped with a JTAG (IEEE Std. 1149.1) boundary-scan register (BSR), a significant number of microprocessors and DSPs can be found with deficient or even non-existent BSRs. CoreCommander Micro uses the on-chip debug mode of processors to access ports and embedded peripheral controllers to promote 'kernel-centric' testing. Similarly, in the case of today’s Field Programmable Gate Arrays (FPGAs) test engineers can 'bridge' from the JTAG interface to the resources of the gate array itself. Our CoreCommander FPGA product implements a 'translator' interface that allows our JTAG hardware to control embedded IP cores via a variety of bus interfaces (e.g. Wishbone, CoreConnect Avalon etc.).

  • JTAG control of 'processors, and FPGAs via core debug access or embedded logic
  • Most popular cores & FPGAs supported
  • Create 'at-speed' cluster tests and flash applications
