Tiliqua is a powerful, open hardware FPGA-based audio multitool for Eurorack. It looks like this:

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: TheAmaranth HDL andAmaranth SoC projects.
• USB and SoC gateware: TheLUNA and Cynthion projects.
• RISCV softcore: TheVexRiscv and SpinalHDL projects
• USB audio gateware and descriptors: Theadat-usb2-audio-interface project.
• Some gateware (e.g. I2C state machines) are inherited from theGlasgow project.
• Audio interface and gateware: my existingeurorack-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 firmwarepico-dirtyJtag

We would like to acknowledge partial funding of theTiliqua project from theNGI Commons Fund, a fund established byNLnet with financial support from the European Commission’sNext Generation Internet program.

The hardware and gateware in this project is largely covered under the CERN Open-Hardware License V2 CERN-OHL-S, mirrored in the LICENSE text in this repository. Some gateware and software is covered under the BSD 3-clause license - check the header of the individual source files for specifics.
