Modern integrated circuits depend on controlling relative timing of signals with picosecond accuracy. Their burgeoning complexity requires many approximations during design. Relatively large design margins are required to account for variations due to manufacturing tolerances. Voltage and temperature variations, intentional or incidental, may also affect signal timing and cause timing errors. Adaptive Delay Sequential Elements (ADSEs) are intended to correct timing errors whether they are caused by manufacturing tolerances, modeling approximation, or voltage/temperature variations.
