在Block Design中实例化自定义设计AXI主机接口驱动(AXI_tansaction.v)、AXI从机接口(MPSoC-IP),并使用AXI_Interconnect-IP进行连接,通过地址定义,将AXI接口指向MPSoC端的DDR4存储器,添加axi_protocol_checker-IP以及ila-IP对通信过程中的关键信号进行抓取和监测; 实例化BD、外部数据激励以及结果统计模块。 3.2 写过程...
AXI(Advanced eXtensible Interface)是Xilinx FPGA中常用的接口协议,Vivado中很多IP都是采用AXI接口,特别是在Block Design模式下,添加AXI接口类的IP,可以发现AXI接口都是合并聚拢在一起的,连接同类型接口,只需连接一根线即可实现接口整体连接,非常方便。 那么对于我们自定义verilog模块,带AXI接口时,如何在导入Block Design...
There are various versions of AMBA like AMBA 1.0 to AMBA 5.0 in which AXI4 lite is an advanced extensible interface targeted for register style interface, it comes under AMBA4.0 specification. AXI4 is having excellent throughput, than AHB.Harini H GKavitha V...
最后,需要选择HDL类型、ISE工程支持和软件驱动模板。因为我比较习惯使用verilog,因而使用verilog模板。需要说明的是,IP接口仍然是VHDL编写,只是用户逻辑改用verilog。如果不需要使用软件驱动模板的话,可以不选上。这里选上了,但是后续编程的时候我并没有用。 最后给出了外设的信息summary。支持,my_axi_ip"外壳"基本完成。

Our code is written in standard SystemVerilog (IEEE 1800-2012, to be precise), so the more important question is: Which subset of SystemVerilog does your EDA tool support? We aim to be compatible with a wide range of EDA tools. For this reason, we strive to use as simple language cons...
VALID和READY信号的先后顺序有一下三种形式: 三、基本事务 AXI4-Stream跟AXI4的区别就是AXI4-Stream去除了地址线,这样就不涉及读写数据的概念了,只有简单的发送与接收说法,减少了延时。由于AXI4-Stream协议(amba4_axi4_stream_v1_0_protocol_spec.pdf... ...
