Abstract
A method for performing timing analysis comprising inputting circuit timing information for a circuit, including temporal constraints between events of a desired circuit operation. A timing diagram representing the desired circuit operation, based on the circuit timing information is generater. All violated constraints within said timing diagram are identified. The method forces no violations of said violated constraints by designating the violated constraints as Non-Breakable (NB) constraints, such that a time difference from a source event to a destination event which defines said NB constraint is no less than a minimum bound and no more than a maximum bound of a linear constraint representing a timing requirement between the source and the destination events.
