MAGIE Hardware

Hardware of MAGIE (Multichannel Acquisition Gigabit Interface Engine), a retargetable FPGA-based acquisition platform developed at the Integrated Systems Laboratory (IIS), ETH Zurich.

This repository contains the KiCad sources and documentation of the MAGIE boards:

• the baseboard: an AMD Kria K26 carrier that connects high-density biosensor arrays to the FPGA fabric and streams their data over 10 Gbit/s SFP+ Ethernet;
• the ultrasound boards: a 64-channel ultrasound pulser frontend and two boards for testing it.

MAGIE baseboard with the Kria K26 SOM and the fan-out board carrying the biochip.

Boards

Board	Folder	Revision	Description
Baseboard	hw/baseboard/	V2.1	Kria K26 carrier with SFP+, 1 GbE, biochip supplies, 16 bias outputs and a 240-pin biosensor connector
Pulser frontend	hw/pulser_frontend/	1.1	64-channel ±100 V ultrasound transmit frontend
Frontend tester	hw/frontend_tester/	V1	Adapter from the pulser frontend's PCIe x16 card edge to an FMC connector
Pulser interface tester	hw/pulser_interface_tester/	V1	Break-out of the 64 pulser channels to headers and SMA connectors

Each board folder is a self-contained KiCad project with its own README, which covers the board, its connectors, known errata and how to generate the manufacturing outputs.

Opening the designs

Open the .kicad_pro file in a board folder with KiCad 10.0. The schematics and PCBs contain embedded copies of all symbols and footprints, so you can view, check and fabricate the designs without extra libraries.

Some vendor 3D models are not redistributed. The boards that use them have a 3d_vendor/README.md that explains where to get them.

Safety

The pulser frontend and the pulser interface tester carry pulses up to ±100 V. Read the safety notes in their READMEs before you power them.
