When designing large-scale, multi-million gate devices, the overriding concern is turnaround time. The EDI System has the capacity to handle such large-scale designs using the flat implementation flow. Major improvements to the design infrastructure, such as multiprocessing and precise correlation throughout the integrated design environment from implementation to signoff have enabled both tremendous performance improvements and greatly enhanced quality of results.
"Today's LSI has clearly shifted to become large scaled due to the increased use of IP, while the market window has drastically narrowed," said Nobuo Tamba, Ph.D., general manager of the Design & Development Operation, Micro Device Division, Hitachi Ltd. "Hitachi is continuously aiming to provide the best-performance, best-quality products, so it is critical for Hitachi to shorten the design time for large-scale LSIs. We adopted the Cadence Encounter Digital Implementation System that brought us a remarkable design efficiency to complete 10 million gates per week. We strongly believe that such a short design turnaround time will be a significant advantage for our large-scale designs."
The EDI System's masterplan automatic floorplanner, high-speed prototyping floorplan verification, and multi-threaded processing at each stage were major contributors to the quick, five-week implementation of the 50-million-gate designs. Along with the EDI System, Encounter Timing System enabled Hitachi designers to quickly analyze and optimize timing for the large-scale design and lead to faster design closure with a significant gain in productivity. The parallel processing function in Cadence QRC Extraction contributed significantly to the turnaround time reduction at the signoff stage.
"The EDI System represents a new generation of implementation solutions with its fundamental new architecture and end-to-end multicore backplane to address the requirements of very large-scale designs. It also delivers a complete solution for low-power, mixed-signal, and advanced-node design, including full embedded electrical signoff and DFM," said Dr. Chi-Ping Hsu, senior vice president of research and development for the implementation group at Cadence. "We're very pleased to have assisted Hitachi in creating this complex, large-scale design, and this success is further evidence of Encounter enabling breakthrough results for our customers."
