Blaze DFM, a Sunnyvale, Calif. maker of software for fabless semiconductor companies to give them greater control over manufacturing design and efficiency, has raised $10 million in venture capital.

It has also completed an acquisition of Aprio, a Santa Clara, Calif. company with operations in Japan and Taiwan that also provides semiconductor manufacturing design software.

From the announcement:

The combined company will continue on as Blaze DFM, Inc. New to the ranks of Blaze investors are El Dorado Ventures and Mobius Venture Capital, both of whom are previous investors in Aprio and are adding fresh capital to Blaze’s Series B round. Lightspeed Venture Partners, who led Blaze’s Series A funding [$6M], also participated in this latest round.

Blaze provides electrical DFM software solutions that maximize parametric yield for sub-100nm chips. Parametric failures • chips that fail to meet timing and power specs • have been described as the most critical yield-limiting factor facing designers today. Maximizing parametric yield has become the top priority at many of the largest chip companies worldwide.

The combination of Aprio’s litho simulation and analysis engines together with Blaze’s electrical analysis and optimization technology will result in the most comprehensive electrical DFM offering available from any commercial vendor.

The Aprio acquisition price was undisclosed. Aprio had raised at least $16 million, and was backed by Mobius and El Dorado as well. KT Venture Group and Goldman Sachs also invested.
