关于楼主位的报错,我发现把delay_clk和和ref_clock接同个时钟就不会报错了
但有个新的问题,编译会报错IDELAYCTRL不够用,我的设计中的用了29对IO,编译器为每对IO都分配了独立的IDELAYCTRL,所以肯定会不够
但是看资料的话,一个时钟域其实用一个IDELAYCTRL就够了,我尝试把IP的IDELAYCTRL屏蔽掉,但会在顶层只例化一次,但也还是会报类似错误
这个问题怎么解决呢,请指点一下吧,非常感谢!
[Place 30-640] Place Check : This design requires more IDELAYCTRL cells than are available in the target device. This design requires 29 of such cell types but only 6 compatible sites are available in the target device. Please analyze your synthesis results and constraints to ensure the design is mapped to Xilinx primitives as expected. If so, please consider targeting a larger device. |
