• UltraScale Architecture Clocking Resources User Guide (UG572) [Ref 3], provides more information on the mixed mode clock manager (MMCM) and clocking. UltraScale Architecture GTH Transceivers UG576 (v1.6) August 26, 2019 www.xilinx.com Send Feedback 17 Chapter 1: Transceiver and Tool ...
路线二:根据User Guide,从时钟布局,到CPLL再到PLL的路线 (1)整体介绍 如下图所示,外部参考时钟GTREFCLK0/1必须通过BUFDS_GTE2原语后才能对PLL输入参考,在路线一可以看到确实如此。当我们选择CPLL工作时,参考时钟经过IBUFDS_GTE2后会直接进入对应通道的GTHE2_CHANNEL,给对应的CPLL提供参考时钟。 而但选择QPLL工作...
The process of configuring the FPGA is explained in detail in the UltraScale Architecture Configuration User Guide, (UG570). For the UltraScale GTH/GTY transceiver (not UltraScale+ GTH/GTY) under certain conditions there can be significant current loading on the power supplies MGTAVCC, MGTAVTT ...
Flow diagram and step by step UltraScale+ GTH Eye Scan: Once the transceiver is correctly set up and working, the basic Eye Scan goes through the measurement loop of the FSM. A "realignment sequence" might be necessary if the offset sampler counts errors, but there are no data errors. In...
