When it comes to the past, everyone writes fiction. ― Stephen King

👀 What's Changed

We keep saying that but this latest release of fiction is again the biggest one yet 💪 It is packed with another year's worth of research and marks a milestone on our mission to bring you the best FCN framework in the world 🌍 Let's dive into v0.6.0 together.

Python Bindings

A long time in the making, finally official: Python bindings for fiction's C++ header-only library 🐍 You can now combine the flexibility of Python's ecosystem with the performance of C++ to explore the world of FCN for yourself. Since we publish pre-built wheels on PyPI, utilizing fiction in your project is merely a pip call away:

pip install mnt.pyfiction

Many, many thanks to @Drewniok and @simon1hofmann who contributed greatly to the bindings! 🙏

SiDB Simulation

We doubled down on what we started: @Drewniok made sure that SiDB simulation in fiction has never been more powerful. This release includes his exhaustive ground-state simulation engine QuickExact, the fastest in the world! ⚡ It is also available as a plugin for SiQAD thanks to @samuelngsh's guidance.

Furthermore, for the first time ever, we feature temperature-aware and atomic defect-aware simulation, automatic exhaustive gate design, and efficient operational domain computation algorithms. Moreover, all these methods now work on the H-Si(100)-2x1 and H-Si(111)-1x1 lattice orientations. Many thanks to @samuelngsh for the ongoing collaboration!

Physical Design

Naturally, we kept pursuing our goal of closing the design gap between conventional VLSI and FCN. @simon1hofmann brings you his post-layout optimization and wiring reduction algorithms that greatly reduce the area and delay of FCN layouts. Furthermore, his hexagonalization enables the transfer of knowledge from the QCA domain to SiDB layouts 🤯 like our new SAT-based clock number assignment algorithm.

In an effort to bring the worlds of physics and design automation closer together, we enable atomic defect-aware physical design to evade material imperfections during placement and routing. Many thanks to @jeremiah-croshaw for the collaboration!

Miscellaneous

As always, we smashed bugs wherever we found them 🐛 we worked on usability, improved performance, updated all libraries to their latest versions, overhauled the documentation and build system, extended the CI setup, and reached 98%+ code coverage on CodeCov ☂️ Many more changes small and big hide in the full release notes. Check them out below. Thanks here go to @wlambooy and @hibenj who made their first contributions 🎉
