One of the most time consuming tasks for users of HDL languages is coding test benches to verify the operation of their design. In his book "Writing Testbenches," Janick Bergeron estimates that 70% of design time is spent verifying HDL code models and that the test bench makes up 80% of the total HDL code generated during product development. In this paper we propose the use of automatic code generation tools to reduce the time required to create and maintain test benches.

A testbench is a verilog program that wraps around an actual design. The testbench is typically not part of the design and does not result in actual circuitry or gates. Verilog code for testbenches may be much more "free style" than Verilog code that must be synthesized - anything goes.
