How do I estimate the resource requirements for my FPGA design?

Estimating FPGA resources involves several factors: 1) Logic cells - count flip-flops and LUTs needed for your logic, 2) DSP slices - calculate multiply-accumulate operations for signal processing, 3) Block RAM - estimate memory requirements for buffers and FIFOs, 4) Transceivers - determine high-speed serial link requirements, 5) I/O pins - count external interfaces and voltage requirements. Xilinx provides resource estimation tools in Vivado. Start with 20-30% margin for future expansion. Contact FAE for architecture review and resource planning.
