Abstract
A number of logic state catching circuits are described which use a logic circuit with a first input, a second input, and an output. The logic circuit is configured to respond to a change in state of a data value coupled to the first input causing a representative value of the data value to be generated on the output. The second input receives a latched version of the data value to hold the representative value on the output after the data value has returned to its original state. A latching element is configured to respond to the change in state of the data value by latching the data value and to couple the latched version of the data value to the second input. A reset element is configured to respond to a change in state of a clock input by resetting the latching element.
