We have designed an FPGA Mezzanine card (standard FMC/Vita 57) for high-channel-count electrophysiology, with 128 channels (potentially up to 512), based upon Intan Tech's RHA2132 (2 uV rms input-referred noise), sampled at 25kHz 18bit by AD7982. We are basing our design on the reference design provided by Reid Harrison of Intan Tech for their 16-channel evaluation board. The expected cost of the device should be under 5000$.

In order to have an integrated solution we intend to have as default carrier the Opal Kelly Shuttle LX1, an inexpensive USB FMC carrier with an excellent USB controller. The integrated solution will be completed with software on the PC side to grab to disk continuously and/or display in some fashion all 128 channels.

Our status: We have an alpha card. It has passed most tests---we can grab from any channel at 1MS/s. We have an alpha microcode: it grabs from any channel and stores on the PC.

Our current team: Marcelo Magnasco (Rockefeller University, New York), design. Andres Cicuttin (ICTP, Trieste), schematics + fpga Maria Liz Crespo (ICTP, Trieste), fpga Sanjee Abeytunge (MSKCC, New York) layout Nicholas Joseph (RU) Macintosh drivers

Couples a MAROC ASIC (64 channels each with a fixed threshold discriminator and a slow shaper + sample-and-hold + 12-bit ADC) to a FPGA. Read-out by Gigabit Ethernet (firmware supplied supports IPBus). Multiple boards can be plugged together to increase the channel count. Clocking circuitry compatible with the White Rabbit implementation of PTP. More info at the Wiki page

Tool for generating multi-purpose makefiles for FPGA projects.

Main features:

makefile generation for: fetching modules from repositories simulating HDL projects synthesizing HDL projects synthesizing projects remotely (keeping your local resources free) generating multi-vendor project files (no clicking in the IDE!) many other things without involving make and makefiles

Hdlmake supports modularity, scalability, revision control systems. Hdlmake can be run on any Linux or Windows machine with any HDL More info at the Wiki page
