Synopsys, Inc. (NASDAQ: SNPS), a world leader in semiconductor design software, today announced it has completed its acquisition of HPL Technologies, Inc. (OTC: HPLA.PK), a leader in yield management software and test chip solutions. The acquisition makes Synopsys the first electronic design automation (EDA) company with a comprehensive design-to-silicon flow that links directly into the semiconductor manufacturing process. Synopsys acquired HPL in an all-cash deal valued at approximately $13 million, or $0.30 per share.

A key benefit of the HPL acquisition is that it gives Synopsys direct access to the yield data needed to reduce systematic defectivity. By extending Synopsys' process solutions directly into the fab, Synopsys can help customers accelerate the introduction of new designs by significantly reducing the time it takes to get from concept to manufacturing.
