Discretix and Lauterbach announce a technology alliance that leverages Lauterbach’s TRACE32 PowerTools and Discretix’ Secure JTAG Debug Module. Through the alliance, manufacturers will now be able to securely analyze and debug the microchip components in their devices at any time during product lifecycle. Lauterbach’s JTAG Debugger is an integrated feature of all the company’s TRACE32 modular development systems. The tool enables engineers to debug System on Chip 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. Now Lauterbach’s new Secure JTAG 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 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.
