Remote access to embedded JTAG testing
The System JTAG (SJTAG) study group, which was formed more than a year and a half ago, has been working toward standardizing the processes and methodologies for the deployment of system-level boundary scan applications. At the upcoming ITC exhibition, two of the prime movers behind the SJTAG effort, ASSET and Firecron Ltd., will demonstrate some of the progress that’s been made.
The SJTAG demonstration in the ASSET booth at ITC will consist of a ScanWorks boundary-scan system interacting with a Firecron embedded controller. Test vectors generated by ScanWorks will be dynamically downloaded over a LAN/WAN Ethernet connection into the system where the Firecron (www.firecron.com) boundary-scan controller has been embedded. The vectors will be executed on the system and diagnostic data will be sent back to the remote ScanWorks station for fault isolation and display.
The SJTAG group is comprised of representatives from Motorola, Lucent, Ericsson and other leading technology firms. The SJTAG demonstration incorporates many of the design principles defined by the working group and is seen by the group as a first step toward an open-standard, non-proprietary implementation of system-level JTAG test and programming.
“We have been working with Firecron and the SJTAG group for quite some time on open standards,” said Alan Sguigna, vice president of sales and marketing for ASSET. “System-level JTAG is becoming much more important to OEMs who are seeking higher degrees of fault tolerance and reliability within their systems, and vendor-independent implementations of SJTAG are key to opening that market.”
ASSET’s booth number at ITC is 502.
