OpenSPARC T2 is derived from the UltraSPARC T2 processor. The UltraSPARC T2 processor is industry's first "server on a chip", packaging the most cores and threads of any general-purpose processor available, and integrating all the key functions of a server on a single chip: computing, networking, security, and input/output (I/O), plus tight integration with the Solaris operating system.

By making the source for this design available for a larger community to review and learn from, we expect that ideas around chip multi-threading and multi-core concepts can be explored more freely and openly, and that truly beneficial innovations can be achieved.

OpenSPARC T2 Download for Chip Design and Verification

OpenSPARC T2 chip source code is for hardware engineering community with experience in chip design and verification. OpenSPARC T2 source components are covered under multiple open source licenses. The majority of OpenSPARC T2 source code is released under the GNU General Public License. Source based on existing open source projects will continue to be available under their current licenses. Binary programs are released under a binary Software License Agreement.

This download area is for hardware design and verification engineers, it includes

• Verilog RTL for OpenSPARC T2 design
• Verification environment for OpenSPARC T2
• Diagnostics tests for OpenSPARC T2
• Scripts and Sun internal tools needed to simulate the design and to do synthesis of the design
• Open source tools needed to simulate the design

System Requirements:

• SPARC CPU based system with Solaris 9 or Solaris 10 Operating System
• C/C++ Compiler, if you don't have it download Sun Studio 12 (it's free too!).

Commercial EDA tools Requirements:

OpenSPARC T2 Download for Architecture and Performance Modeling Tools Tools

SAM (SPARC Architectural Model) is a full system simulator that is able to boot hypervisor, OBP (Open Boot PROM) and Solaris and run applications. It loads SAS (SPARC Architecture Simulator) as the OpenSPARC T2 simulator. So any modifications made in SAS get automatically reflected in SAM. SAM is useful for software bringup work -- for instance to debug Hypervisor/OBP/Solaris on a modified CPU implementation. SAM is also useful for performance analysis, both to generate traces and to connect with a performance model to perform execution driven simulation. SAM loads device models as dynamically linked libraries, and is useful for device driver development, and device RTL verification.

Legion is a fast instruction accurate simulator which provides a rapid means of developing and testing software functionality in the absence of actual hardware. Legion provides the fastest simulation environment for developing and testing SPARC Software. Firmware and Software developers will be the primary users of Legion simulation environment for the OpenSPARC T2.
