Using Spectre RF to perform stability analysis for circuits with periodically time-varying operating points.
The PSTB (periodic stability) analysis feature in Cadence Spectre RF Simulation Option performs stability analysis for circuits with periodically time-varying operating points. PSTB is the periodic equivalent of linear stability (STB) analysis in that it calculates the small-signal loop gain, gain margin, and phase margin around a periodic operating point. PSTB is useful in applications such as power amplifiers and oscillators, where linear stability does not apply due to the nonlinear nature of the circuits.

What hoops will designers have to jump through to avoid concurrency bugs?
This new communications standard could transform architectural decisions across the industry, but not right away and not necessarily in obvious ways.
Maximum flexibility is no longer the reliable path to product success. While flexibility must be there for a purpose, it also can be a liability.
Why managing power is becoming more difficult, more critical, and much more expensive.
Analog circuitry stopped following Moore’s Law a long time ago, but that hasn’t always helped.
