To prove your exhaustive testbench will find an error, use a force assignment to override the behavioral code’s sum sometime after 3⁄4 of the test vectors have been applied. Use the ifdef and endif compiler directives to include or exclude the code that forces an error. In your report, include log printouts from both the error-free and forced error cases. Use $monitoroff and $monitoron commands to show only the first dozen or so test vectors (and results) and the last dozen or so for the error free case. For the forced error case, use them to show the first dozen or so test vectors and about a dozen test vectors before and including the forced error

To prove that your exhaustive testbench will find an error, you can use a force assignment to override the behavioral code's sum sometime after 3/4 of the test vectors have been applied. Use the ifdef and endif compiler directives to include or exclude the code that forces an error.

In your report, include log printouts from both the error-free and forced error cases. Utilize the $monitoroff and $monitoron commands to display only the first dozen or so test vectors (and results) and the last dozen or so for the error-free case. For the forced error case, use them to show the first dozen or so test vectors and about a dozen test vectors before and including the forced error.

This approach effectively demonstrates the testbench's ability to identify errors by highlighting the differences in outcomes when an error is intentionally introduced into the process.
