Abstract
A method and apparatus for testing mathematical programs where code coverage is exceedingly difficult to hit with random data test vectors (probability <2−64) is provided. To enable testing of the mathematical program, instructions in the mathematical program are trapped. Errors are injected through the use of any status/control flag where an error can be created and be rectified later by a reversible operation so that the result of the mathematical operation is not modified by the injected error.
