and clk_inst/inst/clkf_buf (BUFG.I) is provisionally placed by clockplacer on BUFGCTRL_X0Y31 产生错误大致原因为: 时钟引脚和MMCM不在一个时钟区域内(The IO port and PLL are not in same clock region hence you are seeing the error. ) 解决办法: 将IO Ports送入的时钟信号通过IBUFG,然后送入...
Check the IS_FIXED property of the BUFG instance to find this out. If the IS_FIXED property is set it means that it is locked by user constraints. If this is the case, modify the constraints so that the I/O port and BUFG get placed in same clock region. ...

由于clock region包含多个tile,而tile由site构成,site又由bel构成,因此,已知clock region,可以很方便地找到其下的tile、site和bel。反过来,已知site或tile,可以找到其所在的clock region。但如果已知bel,则不能直接找到其所在的clock region: set all_cr [get_clock_regions] ...
set_property CLOCK_REGION XxYy [get_cells <bufg_instance_name>] This might fail with a different error which could explain why the tool was not able to place the I/O and BUFG in the same clock region. If the user constraints help in successful placement then this is a tool issue, as...

While building the Hardware_Acceleration/Design_Tutorials/05-bottom_up_rtl_kernel/krnl_aes project, I got some errors at the stage of FPGA logic optimization. My vitis version is 2021.2 and Ubuntu version is 18.04. I found some advice re...
