AXI VIP 中定義自己的define文件

 

Normally, the interface file  “axi_if.sv “ includes a” AxiPortDefines.inc” file , which has lots of `defines with default values, and may mismatch with your real design.  

`define DW_VIP_AXI_ADDR_PORT_WIDTH           64

`define DW_VIP_AXI_ALEN_PORT_WIDTH            10

`define DW_VIP_AXI_ASIZE_PORT_WIDTH           3

`define DW_VIP_AXI_ABURST_PORT_WIDTH          2

`define DW_VIP_AXI_ALOCK_PORT_WIDTH           2

`define DW_VIP_AXI_ACACHE_PORT_WIDTH          4

`define DW_VIP_AXI_APROT_PORT_WIDTH           3

`define DW_VIP_AXI_AID_PORT_WIDTH            32 

`define DW_VIP_AXI_AVALID_PORT_WIDTH          1

`define DW_VIP_AXI_AREADY_PORT_WIDTH          1

 

There are several  ways to specify your own values:

1)      Modify the “AxiPortDefines.inc” file directly;

2)      Create a new file(”myAxiPortDefines.inc”) and specify your own values, then tell axi_if.sv to use your user-defined file;

3)      Override the macros in your TB.
