Abstract
A transparent latch ( ) and a logic conditioning circuit ( ) are disclosed. The transparent latch ( ) receives signals from conditioning circuit ( ), including a test input that indicates whether the transparent latch is in a testing mode or an operational mode. When the transparent latch ( ) is in a testing mode, the transparent latch acts as a buffer or flow-through logic circuitry, permitting the logic circuitry that includes transparent latch ( ) to be tested according to existing test methodologies. When the transparent latch is not in testing mode, the transparent latch ( ) acts as a transparent latch ( ), holding the state of the input when the clock signal is in a first state and allowing the input to propagate to the output when the clock signal is in a second state.
