Mentor Graphics has extended its EDGE MAJIC full-featured JTAG debug probe support to include Cavium Networks' OCTEON 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 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.
Customers with current support contracts can download firmware and software updates from Mentor SupportNet to upgrade their MAJIC probe for the OCTEON Plus family.
