Dave recently implemented an Actel Ignoo Nano and Xilinx Spartan 3 FPGA into a design, so decided to share some rather random notes on how to implement the FPGA’s in this scenario.
From datasheet specs, traps for young players, global clocks, FPGA fabrics, core power supplies and decoupling, getting the schematic basics, JTAG and flash PROM interfaces and finally PCB fanout and routing of a tiny 0.4mm pitch BGA package.
