  • Patent number: 8701063
    Abstract: The number of scenarios analyzed for an electronic circuit is reduced to improve the processing time and resource requirements of electronic design automation processes. Each scenario is associated with a mode and a corner for the electronic circuit. Groups of scenarios corresponding to different corners for the same mode are identified. A winner scenario from each group is identified, for example, by selecting the dominant scenario from the group that covers the most number of violations in the group. The winner scenario is adjusted to account for violations of other scenarios of the group. The adjustment corresponding to a violation for a timing node from another scenario is performed by reducing the required time of the timing node in the winner scenario by a margin. The margin is determined based on timing information from the other scenario scaled to account for differences between the two scenarios.

  • Patent number: 8681461
    Abstract: Some embodiments relate to an electrostatic discharge (ESD) protection device to protect a circuit from an ESD event. The ESD protection device includes first and second trigger elements. Upon detecting an ESD pulse, the first trigger element provides a first trigger signal having a first pulse length. The second trigger element, upon detecting the ESD pulse, provides a second trigger signal having a second pulse length. The second pulse length is different from the first pulse length. A primary shunt shunts power of the ESD pulse away from the ESD susceptible circuit based on the first trigger signal. A current control element selectively pumps current due to the ESD pulse into a substrate of the primary shunt based on the second trigger signal.
