4/19/2004 - Synplicity Inc. (Nasdaq: SYNP), a leading supplier of software for the design and verification of semiconductors, announced it has enhanced its IdentifyTM RTL debugging software with major new features to extend its capabilities for FPGA and ASIC prototype hardware debugging. The Identify 2.0 software now features a fast and safe incremental flow for Xilinx FPGAs that allows designers to first debug specific signals in their hardware and then change those signals in a matter of minutes, thereby enabling a real-time, debug-centric verification approach. With this new RTL incremental flow, the available signals for incremental debug are automatically correlated back to the original RTL source code, taking the guesswork out of FPGA hardware debugging. This latest version of the Identify software also includes support for multiple sample clock views in a single debugger and an improved user interface with a debug project manager, making the tool able to handle complex designs in a more manageable way. Synplicity also announced two new patents, numbers 6,581,191 and 6,618,839, issued by the U.S. patent and trademark office covering the way the Identify technology debugs designs implemented in FPGA hardware using the original RTL source code.
One of the biggest problems with existing hardware debugging solutions is that when designers are not able to find the source of errors, they are forced to run multiple iterations of synthesis and debug insertion. This problem exists because it is difficult for designers to find errors in the post place and route netlist, often because the signal names have changed and there is no way to associate them back to the original RTL source. Because designers are forced to resynthesize the design and go through place and route again, several hours are added to every debug iteration.
“FPGA designers have a huge advantage due to the ability to switch to hardware based verification early,” said Ken McElvain, chief technical officer, Synplicity Inc. “The rapid increase in FPGA design size and complexity has threatened the productivity advantage of FPGA hardware-based verification by increasing the debug cycle time and making it harder to correlate post-synthesis signals with the original RTL design. With our Identify 2.0 software designers have RTL visibility into hardware and fast incremental change in the signals that are monitored, avoiding place and route cycles in design debug. This efficient debug-centric verification flow will yield a significant advantage for both ASIC prototypers and FPGA designers who are trying to reach their markets quickly.”
The incremental flow within the Identify software eliminates the guesswork of finding errors in the design by guaranteeing every signal available for incremental debug is correlated back to the original RTL source. Users wanting to view signals simply open the Identify software instrumentor and request the tool perform an incremental debug session. Instead of synthesizing the design again, the incremental debug session loads the original debug session, queries a database file and correlates the signals in the design to the place and route files — a process that typically takes only a few seconds. Once it is done, the tool displays the RTL source code, showing the signals it can correlate between the RTL and back-end database files. The Identify solution works closely with Xilinx’s back-end tools, enabling the software to go through incremental place and route in order to reprogram the FPGA.
“Synplicity’s Identify software has proven to be a unique and valuable tool for our customers,” said Rich Sevcik, executive vice president, Programmable Logic Systems Group and the Intellectual Property/Cores and Software Solutions Group at Xilinx. “The ability to do RTL debugging of hardware saves our customers a tremendous amount of overall design time. Now with the addition of the Identify software’s incremental flow, the tool provides a unique ability to debug an FPGA design in a fashion similar to using an RTL simulator but with the tremendous performance advantage of using the actual hardware.”
Increased Project Management
The latest version of the Identify 2.0 software includes a multiple sample clock feature and an improved user interface. With the multiple sample clock, or multi-IICE feature, the software enables designers to deal with multiple asynchronous clock regions in a single debugger window. Inside the debugger window, a user can have multiple tabs that relate to different clock regions within the design, allowing cross triggering between different clock regions. This allows designers to use complex triggering operations on a multi-clock design inside a single debugger window.
All new capabilities within the Identify software are managed under an improved user interface, offering significantly increased project and data management and making the tool easier to use. The instrumentor and debugger both have a project management feature inside the user interface that makes it much easier to load projects and data directly into the software. Another new feature of the software is the ability to save and load sets of trigger conditions allowing designers to save and reuse triggers much like stimulus in a simulator. Both the instrumentor and debugger software are now available for Redhat Linux 7.2, 7.3 and 8.0 as well as Windows 2000 and XP Professional platforms. The instrumentor software is also available on Solaris 7, 8, and 9 platforms.
Unique Technology Advantages
Identify is based on significant new technology that allows a design implemented in FPGA hardware to be debugged using the original RTL source code. Synplicity has already been issued two patents for this technology and has filed several additional patent applications. Synplicity believes this technology is a key differentiator that allows tremendous advantages in reducing the time required to find hardware design problems, allowing users to reduce their verification time by weeks or months.
Pricing and Availability
The Identify 2.0 software will be available in April 2004. Pricing for the Identify software starts at $9,000 (U.S.) for a one-year single vendor time-based license. Multiple vendor and perpetual licenses are also available. Additionally, copies of the Identify LiteTM software are currently being shipped along with the latest version of Xilinx’s Integrated Software Environment (ISETM) and are available for download from the Synplicity website. Identify Lite is a feature reduced version of the Identify 1.3 software that allows designers to test-drive most of the functionality of the full Identify software product. Users of the ISE design environment have access to a promotional software license of Synplicity’s Identify Lite software until August 31, 2004.

About the Identify Software
Synplicity’s Identify software is the only software tool that allows FPGA and ASIC prototyping designers to functionally debug their hardware directly in their RTL source code. This allows functional verification with RTL designs that is up to 10,000 times faster than RTL simulators and enables the use of in-system stimulus for applications like networking, audio and video, and HW/SW designs. The Identify software allows designers to directly select signals and conditions in their RTL source code for debugging and viewing directly in the RTL source code. The software can also save results in standard VCD format that can be used with most waveform viewers.
