1.17 Conclusion

The continuous growth in complexity of electronic designs requires a modern, systematic, and automated approach to creating testbenches. The cost of fixing a bug grows by 10x as a project moves from each step of specification to RTL coding, gate synthesis, fabrication, and finally into the user’s hands. Directed tests only test one feature at a time and cannot create the complex stimulus and configurations that the device would be subjected to in the real world. To produce robust designs, you must use constrained-random stimulus combined with functional coverage to create the widest possible range of stimulus.
