FPGA FMC Breakout Board for Accessing LPC Connections from High End Xilinx FPGA Ultrascale+ Zynq

This post is going to be about Breakout board PCB for FMC Connector which are widely used on Xilinx High End FPGA board. LPC Low pinout connections do not have any GTY or GTH or GTX or MGT connections they have only differential normal SerDes connections ANSI/VITA 57.1 compliant

Schematic 

Schematic has only 4 LPC rows connected directly to Top layer and board layer connector. 1.27 mm Header route out all connections including GND pins all the Signals are routed in Differential connection

Signal Rows in FMC LPC vs. HPC Connector pins Difference

Row	LPC (160 Pins)	HPC (400 Pins)	Function
A	❌ No	✅ Yes	Power, control, & reference clocks
B	❌ No	✅ Yes	Additional I/O and clocks
C	✅ Yes	✅ Yes	Single-ended I/O & differential pairs
D	✅ Yes	✅ Yes	More I/O & differential pairs
E	❌ No	✅ Yes	Additional differential pairs (DP0-9)
F	❌ No	✅ Yes	More differential pairs (DP10-17)
G	✅ Yes	✅ Yes	Primary differential pairs & clocks
H	✅ Yes	✅ Yes	More primary differential pairs & clocks
J	❌ No	✅ Yes	Gigabit transceiver signals (MGTs)
K	❌ No	✅ Yes	More MGTs & ground
