In Chap. 4 you learned how to connect the design and testbench with interfaces. These physical interfaces represent real signals, similar to the wires that connected ports in Verilog-1995. A testbench uses these interfaces by statically connecting to them through ports. However, for many designs, the testbench needs to connect dynamically to the design.
