CAST and FS2 Partner to Provide
Advanced Debug Capabilities for SoC Designs
New Debugging Option Now Available for
8051-Compatible Embedded Processor Cores January 30, 2001, DesignCon, Santa Clara, California
- CAST, Inc. and First Silicon Solutions, Inc. (FS2) today announced a joint effort to make embedded processor cores easier to debug. The resulting option adds FS2's instrumentation intellectual property (IP) and interface to CAST's IP cores, making them accessible and controllable even when buried within complex system-on-chip (SoC) designs. This greatly facilitates system software development, pre-silicon hardware simulation, and first-silicon debug and validation.
The new option is available immediately for the CAST R80515 microcontroller core, and is already in use in the field. The option is also available upon request for other processors in CAST's 8051-compatible family. Pricing varies, but typically starts at about 15% of the standard core cost.
Advanced Features Solve Many Difficult SOC Design Issues
Reaching the control and data pins of an embedded processor from outside the chip is often impossible with complex SoCs. This makes it difficult or expensive to apply conventional debugging tools such as logic analyzers or in-circuit emulators.
FS2's technology overcomes this challenge by making internal cores directly accessible from outside the physical chip. It adds a special On-Chip Instrumentation (OCI[tm]) debug logic block to the synthesizable processor core. A high-performance hardware-assisted debugger is connected to the target system containing the SoC core with a standard JTAG connector. The debugger "box" manages communications between the OCI debug block in the silicon and the Windows® PC development system. Designers control the OCI block and embedded processor through source-level debug software running on the Windows PC.
The OCI block's robust features include run control, memory and register visibility, software and hardware breakpoints, complex breakpoints, and a sophisticated trace history. It doesn't impact the system's logic, and can operate at real-time processor speeds. The OCI is economical in its use of chip area and its extensions are scalable: designers can trade off extra debugging power against extra gate usage during synthesis. The technology can also be extended to support multi-core debug, software performance analysis, and network protocol analysis.
