Reducing the time required to measure constraint parameters (setup time,
hold time and pulse width) of components in integrated circuits. For example, the
delay of propagation of a signal between an input node and an intermediate node
of a component are measured. An approximate range of possible values is formulated,
and a search (by applying signals assuming one of the values in the approximate
range and examining the output signal(s)) is conducted within the range to determine
the value of the constraint parameters.
