1 Timing Constraints: Are they constraining designs or designers? Subramanyam Sripada Synopsys Inc 3/13/2015

2 Constraint Analysis/Debug/Management Budgeting Issues Functional Scan Test Low_Power More Modes More Files/ More complex constraints IP Blocks Reused Cores Blocks Timing Constraints Synthesis, P&R, Signoff Difficult integration of chip-level constraints

3 Constraint Issues Incomplete, inconsistent or conflicting constraints Inconsistent block-level and top-level constraints Automatic generation of timing constraints vs verification of manually generated timing constraints Detection, Debugging and Fixing Dealing with MMMC constraints

4 Panel Details Need of clean SDC for design flows Challenges in generating clean SDC State of current EDA tools What is needed from EDA tools? Panelists – Texas Instruments – Ausdia – Intel – FishTail – Altera – Synopsys

5 Krishna Panda Krishna Panda is STA Technologist at Texas Instruments. He has been responsible Timing and Signal Integrity Signoff for the past three technology Node. He is a Member of Technical Staff at TI. Joined Texas Instrument in He has a Bachelor’s Degree in Electronics Engineering from Mumbai University and has 20+ years of ASIC design experience.

6 Sam Appleton Sam co-founded Ausdia, and drove the early product planning, product development and market analysis for Timevision. Prior to Ausdia, Sam held a variety of technical leadership roles at Azul Systems, Reshape, Cosine Communications and Silicon Graphics. At Azul Systems, Sam drove the implementation & physical methodology for three generations of custom SMP processors, from 500 to 900Mhz and 1.2B transistors. Sam received a Ph.D. in Electronic Engineering from the University of Adelaide, focused on high-performance asynchronous circuit & logic design. He has personally been involved in more than 20 tape outs from 1um to 28nm.

7 Bruce is part of the newly acquired Axxia network processor group at Intel in Allentown PA, working on design methodologies. His areas of focus include static timing analysis, constraint verification, timing closure and low power design techniques. He has been at Intel (previously Avago Technologies, LSI, Agere Systems, Lucent – Microelectronics, AT&T) for 20 years. Prior to that, he was a Field Application Engineer at Racal Redac in NJ, and a Design Engineer at Raytheon in Tewksbury MA. He has received a Masters of Science in Electrical Engineering from Northeastern University, and a Bachelor of Science in Electrical Engineering from the State University of New York at Stony Brook. 7 Bruce Zahn

8 Ajay Daga Ajay received his PhD in Computer Engineering from The University of Michigan, Ann Arbor in Ajay worked in Mentor Graphics and Synopsys before founding, funding and growing FishTail revenues.

9 Tom Spyrou Tom Spyrou has worked for over 25 years as an EDA Technologist and has gained extensive experience in areas including Static Timing Analysis, Logic Synthesis, Power Grid Analysis, Database Technology and Floor- planning. He has lead the development of leading edge commercial engines and products such as PrimeTime, Voltage Storm, First Encounter, and the Open Access Database. He has a BS from CMU in ECE and and MS from Santa Clara. He is currently the Architect of Altera’s new TimeQuest2 STA tool. 9
