Designing with Multi-Gigabit Serial I/O
Learn how to employ serial transceivers in your 7 series FPGA design. Understand and utilize the features of the serial transceiver blocks, such as 8B/10B and 64B/66B encoding, channel bonding, clock correction, and comma detection. Additional topics include use of the 7 Series FPGAs Transceiver Wizard, synthesis and implementation considerations, board design as it relates to the transceivers, and test and debugging. This course combines lectures with practical hands-on labs.
