Cadence stregthens within DFM by the acquisition of Clear Shape.

The move expands Cadence's efforts in DFM. Traditional DFM-enabled lithography analysis products take days or weeks to run, according to Cadence.

"We think there's a lot of momentum to be gained by integrating Clear Shape's predictive, manufacturing-OPC-tool independent, validated-in-silicon lithography capabilities into the Cadence DFM environment," said Atul Sharan, president and chief executive of Clear Shape, in a statement.

The acquisition was completed on Aug. 15. Terms of the agreement have not been disclosed.
