Code-driven analog design for detector readout ASICs — •Kennedy Caisley, Marco Vogt, Hans Krüger, and Jochen Dingfelder — University of Bonn, Bonn, Germany

Readout integrated circuits for pixelated radiation detectors have experienced a renaissance in the past two decades, with over 50 full-reticle chip designs reported in the HEP and photon science communities alone. The adoption of smaller process nodes (from 350 nm down to 28 nm) has generally improved performance, density, and power efficiency; but at the cost of increased design effort.

This talk describes workflows using programming languages like Python, C++, and Rust to design analog readout circuits. Procedural-style code is well-suited for automating 'bottom-up' tasks like schematic device sizing, layout generation, and analysis of SPICE simulation, while 'top-down' optimization routines suitably formalize constraints like silicon area and power consumption.
