Enable transceiver is shown in the linux example of the test_board design. Spartan-6_Clocking_Technical_Module. This is because the BUFH is only partially supported in the Spartan-6 FPGA. It's taken a while for me to get to the point of being able to implement this project, probably about 6 months on and off to get a working, reliable transmitter, starting at. FPGA Clocking • Clock generation (fr equency synthesis) – Uses “Clock Management Tiles” which consist of: • PLL/DCM (Frequency S ynthesis) • MMCM (Adv anced PLL with phase control) – Clock input from PCB must use “Clock capable pins” of FPGA • Differential pairs. Clock Distribution Each Virtex-6 FPGA provides five different types of clock lines (BUFG, BUFR, BUFIO, BUFH, and the high-performance clock) to address the different clocking requirements of high fanout, short propagation delay, and extremely low skew. at Digikey Each BUFH can be independently enabled/disabled, allowing for clocks to be. クロック バッファーを BUFG から BUFH に変更 - BUFG に戻すには (ザイリンクス アンサー 57546) を参照; トランシーバーへのパスを変更 - 形式は /gt0_gt_wrapper_i/gtxe2_i になり、X0Y1 命名スタイルを使用する場合は制約に影響 (ピン パッケージ制約の変更はない). 技术支持; AR# 64793: Aurora 8B10B v11.
