SMIC, Cadence Partner for RTL-to-GDSII Reference Flow

3/17/2003 - Cadence Design Systems, Inc. (NYSE: CDN) and Semiconductor Manufacturing International Corporation (SMIC) announced that SMIC has qualified one of its first-generation reference flows. This flow incorporates the Cadence® EncounterTM digital IC design platform to address nanometer design challenges such as complex hierarchical designs and timing and signal integrity (SI) sign-off. This reference flow was developed using SMIC's 0.18 micron process technology and validated with designs from customers. Cadence is one of the first electronic design companies to launch an RTL-to-GDSII reference flow with SMIC.

"SMIC, the largest foundry and ASIC design services provider in China, has many customers who need to migrate to designs at 0.18 micron and below," said James Sung, vice president of marketing and sales at SMIC. "This means they are facing increasingly difficult design challenges. The SMIC reference flow, fueled by advanced digital IC design technology from Cadence, along with SMIC's process kit, will ensure the highest levels of quality and productivity for our customers."

The SMIC-Cadence Reference Flow 1.0 is a complete RTL-to-GDSII flow. It consists of all necessary design steps, including logic synthesis, simulation, silicon virtual prototyping and physical implementation. This reference flow deploys the Cadence Encounter wires-first continuous-convergence methodology. It allows designers to quickly generate a virtual prototype to identify timing, SI and routing congestion issues early in the design cycle. This enables SMIC's customers to conduct more feasibility studies to determine the best chip scenarios in terms of die size and performance.

In the implementation stage, this flow provides a comprehensive platform for designers to drive RTL-to-GDSII with emphasis on fast, accurate and automatic timing and SI closure. It addresses hierarchical block partitioning, physical timing optimization, 3-D RC extraction, IR drop, and crosstalk glitch and delay analysis. This flow enables designers to refine the virtual prototype and proceed in a systematic, predictable way toward a quality tapeout.

"We are happy to be the electronic design company to partner with SMIC and launch one of its first reference flows," said Mathew Chan, corporate vice president and president of Cadence Asia Pacific. "I believe our engagement with SMIC puts in place another vital link in our customers' design chain, ensuring a manufacturing aware design chain from idea to silicon. It also highlights the growing number of foundries and design houses in China that rely on the Cadence digital IC design flow."
