Looking at the Rev B04 schematics for the XEM8320, the fabric_refclk_c nets, found on page 3, seem to not be connected anywhere in the schematic. They are supposed to connect to T24/U24 on bank 65 but this is omitted from the schematics.
The doc portal for this board shows the following:
CLOCK | FREQUENCY | FPGA PINS (P / N) |
---|---|---|
Fabric | 100 MHz | T24 / U24 (Bank 65) |
DDR4 | 100 MHz | AD20 / AE20 (Bank 64) |
MGT | 125 MHz | P7 / P6 (Bank 226) |
Is there an updated schematic that I can reference or am I missing something there?
Thanks!
