Acknowledgements

This project would be nothing without the hard work of many (awesome) open-source projects. An exhaustive list would take pages, here I mention only a crucial subset:

• Python-based HDL and SoC framework: The Amaranth HDL and Amaranth SoC projects.
• USB and SoC gateware: The LUNA and Cynthion projects.
• RISCV softcore: The VexRiscv and SpinalHDL projects
• USB audio gateware and descriptors: The adat-usb2-audio-interface project.
• Some gateware (e.g. I2C state machines) are inherited from the Glasgow project.
• Audio interface and gateware: my existing eurorack-pmod project.
• SID emulation gateware: reDIP-SID
• The "mi-plaits-dsp-rs" project: mi-plaits-dsp
• The "pico-dirtyJtag" project forms a big chunk of the RP2040 firmware pico-dirtyJtag

Funding

We would like to acknowledge partial funding of the Tiliqua project from the NGI Commons Fund, a fund established by NLnet with financial support from the European Commission’s Next Generation Internet program.
