set_property CLOCK_DEDICATED_ROUTE BACKBONE
时间: 2023-08-06 19:08:47 浏览: 226
您好!对于设置时钟路由的问题,您可以使用以下命令来设置时钟约束:
```
set_property CLOCK_DEDICATED_ROUTE BACKBONE [对象]
```
其中,"[对象]"是您要设置时钟约束的对象名称或路径。通过将属性"CLOCK_DEDICATED_ROUTE"设置为"BACKBONE",可以告诉综合工具将该时钟信号专用于主要的时钟网络。
请注意,具体的设置方法可能因为您使用的综合工具或目标设备而有所不同。这只是一个示例命令,请根据您的实际需求进行调整和使用。
如果您有其他问题,请随时提问!

[Place 30-575] Sub-optimal placement for a clock-capable IO pin and MMCM pair. If this sub optimal condition is acceptable for this design, you may use the CLOCK_DEDICATED_ROUTE constraint in the .xdc file to demote this message to a WARNING. However, the use of this override is highly discouraged. These examples can be used directly in the .xdc file to override this clock rule. < set_property CLOCK_DEDICATED_ROUTE BACKBONE [get_nets sys_clk_IBUF] > sys_clk_IBUF_inst (IBUF.O) is locked to IOB_X1Y74 instance_name/inst/mmcm_adv_inst (MMCME2_ADV.CLKIN1) is provisionally placed by clockplacer on MMCME2_ADV_X1Y2 The above error could possibly be related to other connected instances. Following is a list of all the related clock rules and their respective instances. Clock Rule: rule_mmcm_bufg Status: PASS Rule Description: An MMCM driving a BUFG must be placed on the same half side (top/bottom) of the device instance_name/inst/mmcm_adv_inst (MMCME2_ADV.CLKFBOUT) is provisionally placed by clockplacer on MMCME2_ADV_X1Y2 and instance_name/inst/clkf_buf (BUFG.I) is provisionally placed by clockplacer on BUFGCTRL_X0Y31
Based on the provided information, it seems that there is a sub-optimal placement for a clock-capable IO pin and MMCM pair in your design. If this condition is acceptable, you can use the CLOCK_DEDICATED_ROUTE constraint in the .xdc file to demote the message to a WARNING. However, using this override is highly discouraged.
To override this clock rule, you can add the following line in the .xdc file:
```
set_property CLOCK_DEDICATED_ROUTE BACKBONE [get_nets sys_clk_IBUF]
```
Please note that this error could possibly be related to other connected instances. The related clock rule "rule_mmcm_bufg" seems to be passing, but it's important to review all the clock rules and their respective instances to ensure proper placement.
If you have any further questions or need additional assistance, feel free to ask.
set_property CLOCK_DEDICATED_ROUTE FALSE [get_nets clk_wiz_main_inst/inst/clk_in1_clk_wiz_main]
这是一条设置时钟约束的命令,将时钟网络"clk_wiz_main_inst/inst/clk_in1_clk_wiz_main"的CLOCK_DEDICATED_ROUTE属性设置为FALSE。这个属性表示是否要求时钟网络完全专用于时钟传输。通过将其设置为FALSE,允许时钟网络与其他信号共享路由资源。
