Patent ID: 7133795

Claim:
A method for testing an electronic system, the method comprising: intercepting an initial signal of the electronic system; modifying the initial signal with a distortion to form a distorted signal; introducing the distorted signal into the electronic system in place of the initial signal; and obtaining, from the electronic system, a result having one of (i) a first value indicating that the electronic system handled the distorted signal in a normal operating mode, and (ii) a second value indicating that the electronic system handled the distorted signal in an error handling mode which is different than the normal operating mode; wherein the electronic system is a computer system; wherein intercepting the initial signal includes: receiving, as the initial signal, a serial data stream which is generated dynamically by the computer system in response to computerized operations performed by individual devices of the computer system; and wherein receiving the serial data stream includes: obtaining, as the serial data stream, a non-static, real-time electrical signal en route from a first device of the computer system toward a second device of the computer system.
