6.10.1.5. FMC Loopback Card
The Arria® 10 FPGA development kit provides two FMC mezzanine interface ports connected to the Arria® 10 FPGA for interfacing to Intel® FMC add-in boards as shown in the figure below. The Intel® FMC interface is mechanically compliant with the Vita 57.1 specification for attaching a double width mezzanine module. However, in terms of signal connections, the Intel® FMC interface is not fully compliant with the Vita 57.1 specification. Instead, it contains a subset of the Vita 57.1 interface signal to the connector as shown in the FMCA and FMCB signal assignments tables.
The following shows the complete signal connections assigned for each Intel® FMC interface at the FMCA port (J1) and FMCB port (J2). For the signal connections to the FPGA device, refer to Table 34.
