Mentor EDGE MAJIC JTAG Debug Probes Support Cavium OCTEON Plus Processors

Mentor Graphics Corporation (Nasdaq: MENT) announced extension of the EDGE(tm) MAJIC® full-featured JTAG debug probe support for the Cavium Networks OCTEON(tm) Plus multicore processor family. The MAJIC series probes speed up platform-level design by giving developers access to the innermost working of their platform, to download code, program flash, and to invoke target-specific support files.

Designed for a multicore environment, the MAJIC series probes provide JTAG connection to the debug support unit designed into each OCTEON Plus cnMIPS core. The MAJIC-MT model supports concurrent connections to the multiple cnMIPS 64-bit cores to facilitate and reduce time required for code development and debug for any combination of cnMIPS cores. In addition to fundamental debug capabilities, the MAJIC deliverables include software interfaces to support multiple development tool environments, including any Linux environment such as Cavium’s own SDK implementation, as well as control of Octeon’s Global-Stop on-chip hardware support to enable hardware synchronized debugging for user-specified core combinations. The MAJIC probes also support Cavium’s register definition files. The MAJIC JTAG supports the “public” MIPS register files out-of-the-box and includes target initialization files for standard Cavium Networks reference designs.

“Robust and field-proven development capabilities for our OCTEON Multicore MIPS64 processors such as those provided by the MAJIC probe and its associated software components continue to be important to our mutual customers,” said Rajiv Khemani, vice president of marketing and sales for Cavium Networks. “The Mentor tool offering coupled with OCTEON’s unique and extensive multi-core debug capabilities enable more efficient platform design while shortening the design cycle.”

“Mentor continues to evolve the MAJIC probe and supporting files to complement the latest multicore processor offering from Cavium,” said Neil Henderson, general manager, Mentor Graphics Embedded Systems Division. “Application platforms looking to adopt the OCTEON Multicore MIPS64 processor solutions are now supported by the same field-proven MAJIC JTAG probe that accelerates the time to market for Cavium Networks multicore designs.”

Customers with current support contracts can download firmware and software updates from Mentor SupportNet to upgrade their MAJIC probe for the OCTEON Plus family. MAJIC is available through Mentor Graphics ESD sales and distribution channels worldwide. Mentor’s MAJIC tools for the Cavium Networks OCTEON Multicore MIPS64 processors have been available since the first introduction of Cavium’s CN3860 family in 2005.
