Audio Video Eurorack based on open FPGA software

Tiliqua

Based on Amaranth HDL software

Sebastian Holzapfel, of German open source audio hardware specialist apfelaudio, wants to put a little FPGA in your Eurorack synthesizer setup — literally, with the Tiliqua module.

"Tiliqua aims to make FPGA-based audio and video synthesis accessible to everyone," Holzapfel explains of his creation. "The Tiliqua hardware architecture, alongside a comprehensive collection of example projects built in Python (Amaranth HDL [Hardware Description Language]), allows you to experiment with synthesis techniques that are out of reach of embedded microcontroller-based platforms. Think extreme oversampling for alias-free audio-rate modulation, low-latency effects, video synthesis, and high-speed USB audio."

Tiliqua itself, designed to slot straight in to a Eurorack setup, is based on an open-hardware FPGA module dubbed the soldiercrab and built around the Lattice ECP5 field-programmable gate array chip, with 25k logic elements, 16MB of HyperRAM/octal-SPI RAM, 16MB of SPI flash, and a high-speed USB PHY. This connects to a motherboard that offers a switched rotary encoder with bar-graph display, the FPGA's USB port and a debug port handled by a Raspberry Pi RP2040 microcontroller, two expansion ports, a 720p60 display output, and a MIDI input jack.

Colorlight i5 is supported
