In September 2012, Cadence held its second Mixed-Signal Summit in San Jose, California. 150 users attended the Summit. The full day program was packed by user presentations. Strong participation and attendance was yet another confirmation of increased design activities in the mixed-signal area. Attendees used the opportunity to ask questions, share experiences and network.
Dr. Chi-Ping Hsu, Cadence Senior Vice president of R&D, welcomed the participants and opened the event. He pointed to Cadence's strong investment and leadership in mixed-signal solutions.
Prof. Ali Niknejad of the University of California at Berkeley delivered an inspiring academic keynote "Pushing the Frontiers of Silicon: Digital RF, mm-Wave, and THz Communication and Imaging." He shared with the audience his research on RF circuit design and silicon implementation for energy efficient, wider bandwidth communication in the 60 GHz frequency range. In second part of his keynote, he discussed design challenges and techniques for silicon-based, reflection-sensing radar imaging, which could potentially replace today's expensive X-ray Computed Tomography (CT) scanners with much less costly solutions for medical imaging and diagnosis.
Chris Collins, Director of Analog EDA and Design Services at Texas Instruments delivered the industry keynote "Tribulations of Combining Analog and Digital Design." In a very entertaining way, Chris shared some of his experiences in deploying an advanced, productive and scalable flow for mixed-signal design. He stressed the importance of a close relationship and collaboration with Cadence for the success of his projects.
Dr. Monte Mar of Boeing Corp. talked about statistical behavioral modeling for sensitivity analysis of analog circuits in order to make feasibility tradeoffs, and choose more suitable circuit topologies and specifications for practical implementation in a top-down design methodology.
Frank Nothaft and Nishant Shah from Broadcom presented a methodology for validating and maintaining a portfolio of AMS IP behavioral models used in SoC verification. They particularly focused on a high level of automation for checking the equivalency of models with their corresponding circuits through efficient regressions.
Prashanth Aprameyan from Micron Technology focused on a comprehensive mixed-signal verification solution for NAND memory using SPICE/fast-SPICE simulation for verifying performance and IR drop impact, and complementing it with "wreal" type Real Number Modeling for full chip functional verification.
Tim Guglielmo and Subodh Reddy from Maxim Integrated shared their findings on the Schematic Model Generation (SMG) tool they evaluated in early partnership program with Cadence. The tool makes it easier for analog designers to create and verify behavioral models using a schematic environment, rather than writing them in a text editor.
Dinraj Shetty and Joaquin Bartra from Spansion talked about their physical implementation flow. Interoperable on OpenAccess, the flow enables analog and digital layout designers to share and refine floorplans with pre-routes done by a custom router which are honored by digital physical synthesis. Designers can easily take the design back to a custom platform for chip assembly.
Mahesh Tirupattur from Analog Bits, and Kumar Keshavan from Sigrity which is now part of Cadence, jointly presented on IBIS algorithmic modeling (IBIS-AMI) for effective channel simulation, applied to 10 Gbps SerDes.
Jim McCanny and Ben Farhat from Cadence discussed the increased importance of static timing analysis for mixed-signal designs, and presented a methodology for characterizing timing of custom circuits and full chip timing analysis using a glass-box (instead of black box) approach.
I had the pleasure of teaming up with Dominic Pajak from ARM to present on CortexTM-M processor benefits for mixed-signal applications, and simulation flow for hardware/software verification.
