Video Interviews

Pravin Madhani, GM Place & Route Division, Mentor Graphics

Video interview with Pravin Madhani, GM of Mentor Graphics Place and Route Division, by John Donovan, Editor/Publisher of Low-Power Design. Conducted at the EDA Tech Forum in Santa Clara, CA, September 9, 2009. In particular we wanted to know:

  • Just how do your place and route tools interact with the other design tools in the tool chain? Do they rely on a common database, or do they accept constraints from the tools above them in the tool chain or design rules from the foundry?

  • At 32 nm and below a few atoms difference in doping can cause a gate to fail. How can you do reliable physical verification considering the wide variations that can be expected during manufacturing?

  • How exactly does multi-corner, multi-mode optimization work? How might it help—and to what extent can it be effective—in increasing the energy efficiency of an SoC design?

  • Finally, what are the major hurdles that physical design and layout software have yet to surmount, and what sort of progress can we hope for in the next few years?
