Abstract

A method can be used for monitoring a processing circuit. The processing circuit generates a response to a request and the response is compared with an expected response. A pass pulse is generated when the response matches the expected response. The causing, comparing and generating steps are repeated a number of times A frequency at which pass pulses occur is evaluated.
