Eindhoven , August 2013 –JTAG Technologies BV (Eindhoven, The Netherlands), a vendor of test and debug tools based on boundary-scan, will showcase the following JTAGLive products as well as new systems upgrades at this years’ ITC show in Anaheim.
JTAGLive CoreCommander – Quick and Easy to Learn and to Use
Engineers can now activate the OCD (On-Chip Debug) modes of a range of popular cores to affect ‘kernel-centric’ testing. While many devices are now equipped with JTAG (IEEE Std. 1149.1) boundary-scan registers (BSRs), which are used extensively to provide test access into digital and mixed-signal designs, a significant number of microprocessors and DSPs can be found with deficient or even non-existent boundary-scan test registers. For the electronics test engineer this can, at best, be ‘frustrating’ as they look to employ alternative methods for testing the ’processor and/or associated cluster/peripheral components.
CoreCommander routines are ideal for diagnosing faults on ‘dead-kernel’ boards in either design debug or repair, since no on-board code is required to set memory reads and writes. Boundary-scan deficient parts can also be better utilised during production test, as CoreCommander-driven functions increase fault coverage. Since CoreCommander is Python-based it complements perfectly the JTAGLive Script product, allowing access to mixed-signal parts such as ADCs and DACs and also synchronised testing to full boundary-scan devices.
The solutions take control of key processor core functions using the built-in emulation/debug functions of the ‘processor core and are designed by test engineers for use by test engineers. JTAG CoreCommander uses dual modes of operation, namely ‘Interactive’ or ‘Python embedded’.
More Features – the new JTAG CoreCommander checks-out the FPGA Zone
CoreCommander for FPGAs is a generic solution based on VHDL code that allows engineers to bridge from the standard JTAG test and programming port (TAP) to proprietary IP cores (e.g. DDR controllers, E-net MAC, USB controllers etc..) and harness them for test purposes.
The base of CoreCommander for FPGAs is a RTL (Register Transfer Language) coded translator block that provides access to proprietary IP cores through commonly implemented bus structures such as ‘Wishbone’, AMBA, Avalon and CoreConnect. This translator block can either be permanently or temporarily programmed into a gate–array. Linker software provided with the module automatically links the translator block with IP blocks and the FPGA specific interface layer to build the complete file set that may be programmed in the FPGA. Access to the translator is subsequently provided by a Python (JFT) library module.
JTAG Live Studio
This is our latest comprehensive package of JTAG/boundary-scan tools that enable designers and manufacturing test engineers alike to develop complete test and programming applications.
The benefits offered by the JTAG Technology for debugging, testing and in-system programming are not limited to complex designs with many JTAG devices. Designs with only a few, even just one or two, JTAG devices can also greatly benefit from this technology during all stages of the life cycle. A toolset capable of handling even the most (very) complex boundary-scan designs, however, often is not economically feasible for a company that only uses a few JTAG devices in its designs.
JTAG Live Studio establishes a new class of test and device-programming tool-set that dramatically lowers the cost of entry for test- and hardware engineers. Alongside the many traditional benefits of JTAG/boundary-scan JTAG Live Studio gives access to newer technologies like processor-controlled test.
Python-embedded mode uses a similar structure to that featured in the JTAGLive Script product, allowing CoreCommander functions to be embedded into Python code to create re-usable test modules for specific tests.
