ERRORlace:1500 - The component u_fiber/txoutclk_mmcm0_i/mmcm_adv_i belongs to
a RPM (its structure is printed below) with 6 instances in the design, and
there are only 2 suitable sites to place such RPMs in the device.
对应的模块如下:
mmcm_adv_i (
.CLKFBOUT (mmcm_clkfbout),
.CLKOUT0 (clk_250), // 250 MHz for pipe_clk
.CLKOUT1 (clk_125), // 125 MHz for pipe_clk
.CLKOUT2 (user_clk_prebuf), // user clk
.CLKOUT3 (clk_500),
.CLKOUT4 (),

报的错误是说MMCM所属的RPM有6个实例,而器件中只有2个合适的地方放置这样的RPM。是不是你选用的器件资源不够,只有两个MMCM?建议核实一下RPM占用的资源都有哪些。
