Ψ-HDL

As the Ψ-family has grown, a practical question has naturally appeared: with several related frameworks now available, which one should you actually use for a particular scientific or engineering problem? The answer is not simply to choose the newest framework, because these methods are not redundant versions of the same idea. Each one was developed [...]

Attribution and scope: this tutorial builds on Ψ-NN, introduced by Liu et al. (2025, Nature Communications). That foundational framework is not my work. Ψ-HDL, Ψ-xLSTM, and Ψ-Vortex are my own extensions of that research direction. The promise of this tutorial: the companion tutorials left our physics-obeying model able to speak „circuit“ through Ψ-HDL and to [...]

There’s a saying floating around the hardware world that sums up one of the biggest mistakes in Edge AI right now: „Don’t kill a mosquito with a cannon.“ Note: Please, never kill insects. They are advanced living beings and deserve respect. If you hurt one by mistake, apologize for it, as I do. Sometimes this [...]

Happy to announce that I’ve taken a meaningful step toward bridging the gap between AI and circuit/device modeling. It is my absolute pleasure to introduce Ψ-HDL (pronounced Psi-HDL), my Physics Structure-Informed Hardware Description Language framework. This work builds directly on the Ψ-NN (Physics structure-informed neural network) discovery framework introduced by Liu et al. (Nature Communications, [...]
