VHDL实现JESD204B，包括testbench测试文件及仿真

# VHDL-JESD204b JESD204b module written in VHDL. Verified against [Xilinx JESD204b IP core](https://www.xilinx.com/products/intellectual-property/ef-di-jesd204.html#overview). The module has had only limited testing and validation. We have got it working with a KCU105 development board and the [AD9164-FMC-EBZ](http://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EVAL-AD916X.html). ## Usage The core needs to be wired to the gigabit transceivers and there are examples provided for 7 series and Ultrascale transceiver wizards and some supporting logic in [examples](examples/README.md). ## Transmit module ### Implemented Features 1. parameters for number lanes (L), octets per frame (M), frames per multiframe (F) specified through module generics. 2. ILA sequence 3. optional scrambler ### Not Yet Implemented 1. PRBS test patterns 2. Lane mapping ## Receive module Not yet implemented. ## License This code is licensed under the Apache v2 license.
