Your XDC file is code. Vivado doesn’t lint it.

Understanding reset timing - recovery, removal, async assert sync deassert, reset trees, and why sporadic startup failures haunt your design

Understanding clock domain crossing - synchronizers, metastability, pulse transfer, gray code, and why 2-flop sync only works for levels

Understanding FPGA resource utilization - LUTs, registers, BRAM, DSPs, and why 94% utilization means your design won’t close timing

Understanding how to add pipeline registers without breaking valid/ready handshakes - skid buffers, register slices, and protocol-correct timing fixes

A deep dive into static timing analysis - understanding slack, path delays, clock skew, and why period minus data path is not your margin

Understanding FPGA timing constraints - clocks, I/O delays, CDC, and why ‘Timing Met’ means nothing without proper constraints

Understanding FPGA timing at 156.25 MHz - where half a nanosecond means the difference between working and failing
