Silicon engineering demands multiple model types — architecture, behavioral, RTL, and test. These typically all use different languages, limiting reuse and forcing teams to maintain disconnected -- possibly inconsistent -- descriptions of the same design.
Zuspec provides a unified Python-based hardware modeling language that covers design and verification. A model written with Zuspec can be can be evaluated statistically, simulated at native-compiled speed, and refined to synthesizable RTL.
Hardware design with Zuspec is progressive: add detail to a shared model instead of starting over at each abstraction. This makes cross-functional collaboration natural, while new synthesizable constructs and design patterns open up a richer micro-architecture design space.

, this time covering some war stories from the past 12 months of getting Tiliqua hardware ready to ship, and all the new features added to the DSP/RTL library since then. Well cover some fun topics such:
* Implementing low-latency USB host purely in gateware
* Dynamic frequency scaling for display switching
* New DSP cores and example projects
* How we are adding first-class fixed-point types to the Amaranth language
* Lessons learned from shipping hardware (and some tricks for passing CE/EMC)
As we walk through each theme, this talk will include some live demos on a small Eurorack system demonstrating each. Tiliqua - Accessible, Reconfigurable Audio DSP Platform (Sebastian Holzapfel)](https://i.ytimg.com/vi/XyGxTcwcONQ/mqdefault.jpg)
