Routing
This section contain block schematics of Sayma AMC board.
I/O connections
General block schematic below shows simplified connections between I/O and components. Some unused connectors were left out to improve readability of this schematic. Front panel connectors (green) and back connectors (blue) are arranged in the same order as in the PCB.
General block schematic
Transceiver connections
Block schematic below shows connections to Multi-Gigabit Transceivers (MGT) of the FPGA. Switches symbolize connections that can be altered by placement of capacitors. Default connection is symbolized by switch position.
MGT schematic with optional connections
Table below outlines connections to MGT ports of the FPGA. If there are two possibilities then the default one is listed first. RTM_MGT connections are TX only by default.

Note
Only port 0 and port 4 are connected to transceivers. Sayma AMC will receive Ethernet only from left (main) MCH slot (though Ethernet is not used by default in Artiq on Sayma). Sayma AMC will only connect to Metlino in left (main) MCH slot.
