Can Xilinx FPGA General IO Be Directly Connected to PLL as Clock Input?

Can Xilinx FPGA General IO Be Directly Connected to PLL as Clock Input?

[Conclusion] General IO cannot be directly used as a clock input for PLL; dedicated clock pins can be used instead. General IO can be connected to the PLL clock input through a BUFG, but the PLL settings must be modified to select “No Buffer” for the input clock option. The specific internal layout can be … Read more

FPGA H.264 Decoder: Verilog Source Code and Project Sharing

Source: EETOP BBS Author: eebinqiu Original: http://bbs.eetop.cn/thread-628991-1-1.html This was first written in 2011, initially supporting only 640×480 resolution on the Cyclone4 E40, without implementing a deblocking filter, and the frame rate was only 25fps. Recently, I took on a project for an H.264 FPGA decoder for drones, which required implementing 720p at 60fps with a … Read more

Q&A with Experts: Unable to Program QSPI Flash in Original Mode During JTAG Boot

Problem Description In the Zynq 1.0 version chip, I attempted to program (erase/write/read) the QSPI in the original mode, but the code hangs when booting in JTAG mode. Solution When the QSPI flash is in the original mode, MIO[5] is connected to the HOLD signal. To ensure that the HOLD signal is not held low … Read more
