zynq7020开发板IP核许可证问题

运用网口传输数据时，在编写sdk遇到如下错误：
[Common 17-69] Command failed: This design contains one or more cells for which bitstream generation is not permitted:
dma_ad_1_i/axi_ethernet_0/inst/mac/inst/tri_mode_ethernet_mac_i/bd_fd03_mac_0_core (<encrypted cellview=””>)
If a new IP Core license was added, in order for the new license to be picked up, the current netlist needs to be updated by resetting and re-generating the IP output products before bitstream generation.
想问一下如何获取IP核许可证
