4 Why FPGA Numerous of digital design can be implemented using an FPGA Economical, very fast turn around time Design and implementation time is short Small designs can be finished and realized in hours Designers can test and verify their designs on-line with the implementation Debugging and correction is much easier Excellent learning platform for students to learn and try different circuits
