LUTRAM资源耗尽的问题

你好,我在工程中出现了如下错误:

[Place 30-504] Global clock placer failed to legalize CLOCKREGION_X0Y3 for clock loads of type LUTRAM. This region contains 5600 available LUTRAM sites, however there are 5712 such loads in the region and clock legalizer could not move enough loads out of the region to legalize it. The following clock nets have loads of type LUTRAM in this region:
Clock net: system_i/system_misc_rtl/axis_clk
Driver: system_i/system_misc_rtl/axis_clk_BUFG_inst
Number of LUTRAM loads: 5633
If the clock net(s) are regional, try using global clock buffers to drive the loads so they are not restricted to specific clock regions and have more freedom to move.

时钟驱动器axis_clk_BUFG_inst已经设置为全局时钟类型BUFG,vivado版本:2017.2,芯片型号:XC7A200T,附件中为report_utilization的log,请问除了更换更多资源的芯片以外还有没有别的方法。 感谢!!!

回复: LUTRAM资源耗尽的问题

不知道用的什么型号的芯片和实现的功能,RAM资源的话7系列的话还可以使用BRAM,UtraScale+的话除了BRAM还可以使用URAM。希望有帮助。
