Abstract
Method and apparatus for detecting an improper voltage levels between a hardware emulator and an auxiliary hardware device are provided. In various implementations, a voltage level detector is attached to a bus that connects an emulator with an auxiliary hardware device. Subsequently, the voltage level detector can be used to detect when operating conditions on the bus are outside specification. More specifically, when the voltage level on the bus falls outside a threshold level, the voltage level detector may be used to alert a user, pause operation of the emulator or both.
