RICHARDSON, Texas — ASSET InterTech Inc. and Firecron LTD will demonstrate System-level JTAG (SJTAG) test and programming in a proof-of-concept system at the European Board Test Workshop, May 24–25, 2006, in Chilworth, Southampton, U.K.
Launched a year ago, the SJTAG industry initiative aims to standardize processes and methods for deploying system-level boundary-scan applications. The SJTAG proof-of-concept system, which was created by ASSET and Firecron, encompasses design principles viewed as a first step toward an open-standard, non-proprietary implementation of system-level JTAG test and programming. The group, chaired by Ben Bennets, Ph.D., includes representatives from Motorola, Lucent, and Ericsson.
A SJTAG demonstrator uses ASSET's ScanWorks boundary-scan test and in-system programming (ISP) platform with Firecron's embedded controller. ScanWorks generates test vectors that are downloaded into the system using Firecron's embedded boundary-scan controller over a LAN/WAN Ethernet connection. Vectors are then executed on the system and diagnostic data is sent back to the remote ScanWorks station for fault isolation and display. The SJTAG platform targets OEMs seeking higher fault tolerance and system reliability. It also aims to reduce no fault found (NFF) issues in the field.
