Error injection to a behavioral model

A computer system for testing an error handler on a simulated hardware comprising:

• a storage element having,
• an error injection mechanism for dynamically injecting an error information including error type and address range, said error information being dynamically injected into any one of a plurality of simulated components of said simulated hardware while said simulated hardware is running, each said plurality of simulated components having a dedicated first user interface module for receiving said error information, said error injection mechanism causing said error type to occur within said address range to test whether said error handler is correctly handling said error type,
• and
• a second user interface module for allowing said dynamic injecting of said error information into said simulated hardware, said second user interface module accepting said error information from said user while said simulated hardware is running and transmitting said error information to said dedicated first user interface module of any one of said plurality of simulated components;
• and
• a processor coupled to said storage element for executing said error injection mechanism.
