// Step 4 - Create a new agent master_agent = new("master vip agent",UUT.AXI_GPIO_Sim_i.axi_vip_0.inst.IF); // Step 5 - Start the agent master_agent.start_master(); 准备就绪,可以发送传输事务了。发送AXI4-Lite 传输事务其实很简单。只需使用 AXI4LITE_WRITE_BURST(addr,prot,data,re...
【AXI4-Lite Read Data Channel】 在示例程序中,AXI Master模块由于数据总线位宽为32bit,因此M_AXI_WSTRB管脚始终输出为:4’b1111 【AXI4-Lite Write response Channel】 【AXI4-Lite Read Address Channel】 其中端口M_AXI_ARPROT,参见【AXI4-Lite Write Address Channel】中的M_AXI_AWPROT 【AXI4-Lite Rea...
master_agent.AXI4LITE_WRITE_BURST(base_addr + addr,0,data,resp); Add the the following code to write 0x0 to the AXI GPIO register 0x0, which should turn OFF the LED //Send 0x0 to the AXI GPIO Data register 1#200ns addr = 0; data = 0; master_agent.AXI4LITE_WRITE_BURST(base_...
2:掌握通过VIVADO工具产生AXI-lite-master代码 3:理解AXI-lite-master中自定义寄存器的地址分配 4:掌握通过VIVADO封装AXI-lite-master图形化IP 5:通过仿真验证AXI-lite-master IP的工作是否正常。 2.2创建axi4-lite-master总线接口IP 新建fpga工程,过程省略 新建完成工程后,单击菜单栏Tools->Create and Package New ...
According to the Platform designer documentation, the AMBA 4 AXI-Lite slave can be interconnected to AXI4 master. However, in such a case, rlast signal is not generated. The problem seems to be related to altera_merlin_bust_uncompressor module which seems to hav...
2:axi-lite-master的axi_awvalid 当start_single_write有效,开始一次写传输,设置axi_awvalid有效。 always @(posedge M_AXI_ACLK) begin //Only VALID signals must be deasserted during reset per AXI spec //Consider inverting then registering active-low reset for higher fmax ...

在 AXI4-Lite 接口上，写操作需要在 WREADY 和 WVALID 信号均为高时进行，数据随后从主接口传输到从接口。写操作完成后，写响应通过 BREADY 和 BVALID 信号传输回主接口，指示写操作是否成功。对于读操作，地址通过 ARREADY 和 ARVALID 信号在主接口和从接口之间传输，数据随后从从接口传输至主接口...

基于前面5篇文章中5个实验,我们已经掌握了AXI4总线协议,现在我们编写一个自定义的AXI-Lite-Slave GPIO IP,并且用编写的AXI-Lite-Master IP对齐进行仿真验证和上板验证。 本文实验目的: 1:修改VIVADO产生的s ... ,UISRC工程师学习站
