John Pierce, product marketing director at Cadence, recently sat down with several analog/mixed-signal design and verification experts for "All Things Analog" video interviews. These short (8-11 minute) video clips offer some good insights into analog verification and simulation, PLL design, low-power design, and mixed-signal systems-on-chip (SoCs). All are now available for viewing on the Cadence Design Systems YouTube channel, as noted below.
In the first interview below, Pierce talked to Ken Kundert, president of Designer's Guide Consulting, and Henry Chang, vice-president at the same company. Kundert and Chang both previously worked at Cadence, and they talked about their move to analog/mixed-signal verification consulting. Chang, who wrote a book on digital verification, noted that the techniques he described in the 1990s are "now becoming applicable in the analog world." Kundert and Chang talked about the challenges of simulating circuits such as audio codecs and sigma-delta converters.

In the second All Things Analog video, Pierce talked to Nandu Bhagwan, president and CEO of GHz Circuits Inc. This interview focuses on the challenges of PLL design and simulation. Bhagwan described how he uses abstraction to run simulations in a reasonable period of time.
In the third video, Pierce talked to Dave Stone, vice president of marketing and sales at Triune Systems, and Ross Teggatz, president and founder of Triune Systems. This company is a fabless semiconductor supplier focusing on "green" solutions, so this conversation naturally turned to low-power design. Stone and Teggatz also discussed the complexity of mixed-signal SoCs compared to older analog designs.
For more information about Triune and a solar power management chip they developed, see my previous blog post or check out a Cadence webinar that described the design challenges behind this innovative chip.
Analog/mixed-signal design and verification is sure to be a big topic in 2012. These videos offer some food for thought to help get the discussion going.
