When designing a real-time system, it is beneh- cial to verify and characterize the system's perform- ance through simulation rather than testing proto- types of the system. The analysis required for verification, however, must be done in a manner that does not impact the simulation. In general, it is use- ful to design an observable system for verification and debugging purposes. Unfortunately, an observa- ble system may not accurately portray or efficiently implement the actual desired system. Most program- mable ICs have simulators with which soflware and hardware can be emulated. They also usually have available evaluation boards on which so&ware can be tested. This publication describes a method for observing the status of a system that does not alter the actual real-time performance of the system or software under test.
