将FPGA高效地集成到PCB中的方法（白皮书）White Paper: Xilinx FPGAs R WP174 (v1.0) March 13, 2003 Methodologies for Efficient FPGA Integration into PCBs By: Philippe Garrault Since their invention, FPGAs have continuously and rapidly expanded in their capabilities. Evidence of this growth is abundant whether one looks at the core programmable logic that went from tens to millions of gates with added arithmetics, memory, clocking, and processing functions or at the I/O ring that has gone from a few I/Os to over a thousand, supporting numerous single-ended and differential standards with on-chip terminations and data rates into the gigabit per second range. The combination of rich feature set with device programmability and re-programmability has made FPGAs highly adaptive to design changes during and after product development an……
