Cerritos, CA, June 12, 2002 -- Corelis Inc. today unveiled three new emulators for Broadcom’s high-performance SiByte BCM1250 dual MIPS64 processor.  The new ScanICE, ScanICE/PIO and the NetICE emulators all utilize the IEEE-1149.1 standard (JTAG) port on the Broadcom BCM1250 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 Ram to collect traces of activity on the internal bus.

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.

Unlike conventional real-time emulators that rely on bulky and expensive external hardware pods, the Corelis emulators use the IEEE-1149.1 (JTAG) standard test access port to access the internal debug resources available for both of the Broadcom BCM1250 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 BCM1250, 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 the processor '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 BCM1250’s two processor cores, which can be independently accessed.  The emulator also supports multiple BCM1250’s in a single boundary scan chain.

“Corelis brings to Broadcom's development platform a wealth of experience in high-performance JTAG emulation and low-cost development tools,” said Krishna Anne, Marketing Manager of Broadcom’s Broadband Processor Business Unit. “These EJTAG emulators will enhance support for customers using the BCM1250 in very demanding and high performance embedded applications.”

“The introduction of this family of EJTAG emulators for the Broadcom BCM1250 will enable the BCM1250 to be more easily integrated into embedded designs and will result in products being brought to market much faster,” said Menachem Blasberg, CEO of Corelis.  “We worked very closely with Broadcom during the BCM1250 development to ensure the highest level of integration and support for the dual processor cores and multiple BCM1250s 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 Flash programming software with the EJTAG emulator speeds the development of boot software.

ScanPlus Runner optional software programs CPLDs and FPGAs in circuit using industry standard SVF, JAM 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-BCM1250 ($6,950), ScanICE-BCM1250/PIO ($5,650) and the NetICE-BCM1250 ($6,950) are available now.
