LONDON Discretix (Santa Clara, Calif) and Lauterbach (Hhenkirchen-Siegertsbrunn, Germany) have set up a technology alliance that plans to enable manufacturers to securely analyze and debug the microchip components in devices at any time during product lifecycle.
The arrangement see Lauterbach's TRACE32 PowerTools integrate with Discretix' Secure JTAG (SJTAG) debug module.
“The joint cooperation between Lauterbach and Discretix gives new options to developers, chip manufacturers and OEMs,” said Norbert Weiss, International Sales & Marketing Manager of Lauterbach. “Through our alliance, these organizations can debug chip errors long after they have reached production stage, giving them better information and greater power for long-term improvement of their products.”
Lauterbach's JTAG Debugger is an integrated in the TRACE32 modular development systems and enables engineers to debug system on chip (SoC) code during development and manufacturing.
Typically, debugging interfaces such as JTAG are disabled as a chip leaves the factory to ensure that no option exists for abuse by hackers or other unauthorized parties.

Lauterbach's has added Secure JTAG (SJTAG) authentication support for the Discretix Secure JTAG debug module enables to keep debugging interfaces active, yet protected. Only parties authorized by the manufacturer can authenticate their Lauterbach's TRACE32 PowerTools, access to the SoC's various parts remains walled off to hackers. Chip manufacturers can also apply a range of access policies.
The Discretix Secure JTAG debug module, suitable for connection using a standard JTAG (IEEE 1149.1) test access port on the debugging PC, can control up to 32 debug domains. The configurable module prevents unauthorized access to internal registers or memories when the device is running and code is available in on-chip memory.
Discretix' Secure JTAG debug module is available as part of its CryptoCell and CryptoFlash security products.
