Cerritos, CA, February 3, 2003 -- Corelis Inc. today unveiled three new emulators for PMC-Sierra’s high-performance RM9000x2™ dual 64-bit MIPS-based multiprocessor.  The new ScanICE, ScanICE/PIO and NetICE emulators all utilize the IEEE-1149.1 standard (JTAG) port on the PMC-Sierra RM9000x2 to provide access to the on-chip debug unit allowing users to debug both processors and the on-chip peripherals.  The emulators can also use the on-chip Trace Buffers to collect traces of instruction execution on each of the processor cores.

The emulators include a powerful Windows™ 95/98/NT/2000/XP based source-level debugger. The ScanICE uses a PCI bus controller that is installed in a PC, the ScanICE/PIO uses a high performance “intelligent” parallel port controller, and the NetICE uses a LAN-based (Ethernet) controller for JTAG emulation access.

The Corelis emulators use the IEEE-1149.1 (JTAG) standard test access port to access the internal debug resources available for both of the PMC-Sierra RM9000x2 processor cores.  This eliminates the need for external pods, thus reducing the cost and electrical loading of the target system.  Since the debug resources used by the emulator are part of the RM9000x2, the emulator automatically supports any clock speed at which the target system runs. In addition to these benefits, the use of the JTAG interface also ensures that processor access is maintained even when a user’s software 'hangs' or otherwise runs out of control. 

Programs and data can be downloaded to the system RAM through the JTAG port without the need for a resident loader program or a ROM emulator. The four-wire JTAG interface allows the emulator to be connected to the RM9000x2’s dual processor cores, which can be independently accessed.  The emulator also supports multiple RM9000x2’s in a single boundary-scan chain.

“Corelis brings to PMC-Sierra's development platform a wealth of experience in high-performance JTAG emulation and low-cost development tools,” said Rob Reiner, Product Marketing Manager of PMC-Sierra’s MIPS Processor Division. “These EJTAG emulators will enhance support for customers using the RM9000x2 in very demanding and high performance embedded applications.”

“The introduction of this family of EJTAG emulators for the PMC-Sierra RM9000x2 will enable the RM9000x2 to be more easily integrated into embedded designs and will result in products being brought to market much faster,” said Jim Rodgers, Technical Marketing Engineer of Corelis.  “We worked very closely with PMC-Sierra during the RM9000x2 development to ensure the highest level of integration and support for the dual processor cores and multiple RM9000x2 devices in a design.”

Options:

• A ROM emulation option for the NetICE allows very fast code download to the target through an Ethernet interface and also allows the insertion of software breakpoints in ROM space.  Real-time emulation of flash memory is also supported.

• In-circuit programming of flash memory using optional ScanPlus In-System Programming software with EJTAG emulator speeds the development of boot software.  This optional software can also be used to program CPLDs and FPGAs in-circuit using industry standard SVF, JAM, J-Drive, and STAPL program file formats.

As an additional benefit, any of the Corelis boundary-scan (JTAG) controllers included with the emulators can be used to provide boundary-scan interconnect testing.  Corelis also has a full suite of boundary-scan test software available that can be used for interconnect and functional testing.  The ScanICE-RM9000x2, ScanICE-RM9000x2/PIO, and the NetICE-RM9000x2 are available now.  Prices, including real-time trace, start from $5,950.
