ila窗口不弹出或ila时钟选择问题

克己树人

我在最近一个项目中使用ila仿真，但板子pl端只有一对200M的差分时钟源，于是我将其接成下图： 时钟设置 将图中的BUFG_O作为ila的时钟源，但是将bit流文件烧进板子上后ila窗口不弹出，具体警告内容如下： WARNING: [Labtools 27-3361] The debug hub core was not detected. Resolution: 1. Make sure the clock connected to the debug hub (dbg_hub) core is a free running clock and is active. 2. Make sure the BSCAN_SWITCH_USER_MASK device property in Vivado Hardware Manager reflects the user scan chain setting in the design and refresh the device.  To determine the user scan chain setting in the design, open the implemented design and use 'get_property C_USER_SCAN_CHAIN [get_debug_cores dbg_hub]'. For more details on setting the scan chain property, consult the Vivado Debug and Programming User Guide (UG908). WARNING: [Labtools 27-3413] Dropping logic core with cellname:'u_ila_0' at location 'uuid_23E7D65A79BC59F7BC47406C1714DFAE' from probes file, since it cannot be found on the programmed device. 导致出现这个问题原因是什么呢？是我选的这个时钟源不是free running clock吗，还是我这个设计存在问题，又或者问题不出在时钟上？希望大家可以给我一些建议或解决办法，谢谢。
