Talk Slides:

Analog and mixed-signal (AMS) circuit layout design is one of few fields in IC design that still significantly behind in terms of automation. The reason behind this is from both the algorithm and software. AMS circuits are sensitive to layout implementation so the industry often relies on human design experience to optimize the layouts. Lacking accessible and easy to use software also raises the barrier to adopt automation tools. The seminar will present some recent results of the AMS layout automation framework MAGICAL, which leverages both machine and human intelligence to produce fully automated analog layouts from netlists to GDSII, including automatic layout constraint generation, placement, and routing. MAGICAL 1.0 has been open-sourced and validated with a silicon-proven 40nm 1GS/s ∆Σ ADC.
