uvm example code of Harness Interface code include apb and axi interface

Here is an example of a UVM testbench harness interface code for APB and AXI interfaces:

// APB interface
interface apb_if (
  input                PCLK,
  input                PRESETn,
  input                PADDR,
  input  [31:0]        PWDATA,
  input                PWRITE,
  input                PSEL,
  input                PENABLE,
  output [31:0]        PRDATA,
  output               PREADY,
  output               PSLVERR
);

// AXI interface
interface axi_if (
  input                aclk,
  input                aresetn,
  input  [31:0]        awaddr,
  input  [7:0]         awlen,
  input  [2:0]         awsize,
  input  [1:0]         awburst,
  input  [3:0]         awid,
  input  [31:0]        awuser,
  input                awvalid,
  output               awready,
  input  [31:0]        wdata,
  input  [3:0]         wstrb,
  input  [31:0]        wuser,
  input                wlast,
  input                wvalid,
  output               wready,
  output [1:0]         bresp,
  output               bvalid,
  input                bready,
  input  [31:0]        araddr,
  input  [7:0]         arlen,
  input  [2:0]         arsize,
  input  [1:0]         arburst,
  input  [3:0]         arid,
  input  [31:0]        aruser,
  input                arvalid,
  output               arready,
  output [31:0]        rdata,
  output [1:0]         rresp,
  output               rlast,
  output               rvalid,
  input                rready
);
