user_reset_out ): 与事务和配置接口交互的用户逻辑必须使用user_reset_out返回其静态状态。该信号与user_clk_out同步地被取消声明,与sys_rst_n异步取消声明。用户侧连接信号(user_lnk_up ):当core和连接设备已准备好互传数据时声明。 ...
IP as the root port for my design, is there any signal in the PCIe hard IP to get to know the PCIe Link Up is done because in some other vendors we will get one output signal named "user_lnk_up" signal that will identify that the PCIe Express core is linked up with a host ...
引脚user_lnk_up,output,当IP核与与之相连的上游的端口进入ready状态,并可相互发送数据包时,该信号变为有效位。 fc_ph[7:0],output,Posted头包流控制认证,定义了该Posted头包流控制的类型。 fc_pd[11:0],output,Posted数据流控制认证,定义了该Posted数据流控制的类型。 fc_nph[7:0],output,非Posted头包...
Connect the input of Utility Vector Logic to “user_lnk_up” of “xdma_0” IP as shown in the image below (the highlighted connection in the below image). Now, right-click on the “Res[0:0]” pin of the Utility Vector Logic IP and select the “Make External” option to make the ...
