Interface的另类用法 --- bind interface in DUT

一、harness interface(AXI4)

• 与以往不同，这个Interface中的信号多定义为port，而非logic。
• 不用modeport

 1.1 下面为一个axi4_if的代码

interface axi4_if#(`AXI4_VIP_PARAMETER_DECLEAR)
(
  //Global Signals  
  input                                    aclk,
  input                                    aresetn,

  //Write Command Channel Signals
  inout [MAX_ID_WIDTH-1:0]                 awid,
  inout [ADDR_WIDTH-1:0]                   awaddr,
  inout [2:0]                              awsize,
  inout [BURST_LENGTH-1:0]                 awlength,
  inout [1:0]                              awburst,
  inout [AWCACHE_WIDTH-1:0]                awcache,
  inout [2:0]                              awport,
  inout [0:0]                              awvalid,
  inout [0:0]                              awready,
  inout [0:0]                              awloc
