YARR: Yet another Rapid Readout

What is YARR?

YARR is a readout system based around the concept of moving intelligence from the FPGA firmware into the host computer software. The role of the FPGA is the one of a reconfigurable I/O interface and not anymore the one of a hardware accelerator. YARR supports multiple types of FPGA platforms:

• COTS PCIe FPGA cards: CERN SPEC, XpressK7, Trenz TEF1001, and Xilinx KC705
• FELIX + NETIO
• FELIX-STAR + NETIO-NEXT
• ATLAS IBL BOC
• Wuppertal's KU040
• BDAQ Hardware

The currently supported readout chips are:

• FE-I4B
• FE65-P2
• RD53A
• ITkPixV1 (RD53B)
• ITkPixV2 (RD53C)
• ABC/HCC STAR

There is very preliminary support for Star chips (strips).

Support

Support for YARR can be found in the YARR Matter Most channel.
