In Q1, a major North American customer of our virtual custom and analog design flow replace the existing digital flow with the Cadence Encounter digital flow in order to deploy a fully integrated mixed signal design flow. A major European customer also renewed a commitment to our mixed signal flow in Q1.
These wins for lower trend we started to see in recent quarters which is the need for integrated mix signal design and verification solution. Our market segment leading Virtuoso product lines enables us to deliver value added solutions when integrated with our Encounter and incisive platforms to meet this market requirement.
In Q1 Virtuoso AMS Designer, our mixed signal simulation product won the 2012 ACE award in China in the category of best EDA product. AMS Designer is used to verify mixed signal SoCs like those used in mobile devices. DSM Technology is a key requirement for manufacturing SoCs at advance process nodes.
We work closely with Samsung foundry to develop DSM flows for in-design optimization and physical sign-off for 32, 28 and 20-nanometer SoC designs. This new flows improved chip yield by addressing critical random and systematic yield issues. We are seeing an increase in interest for design solutions for 3D-IC. Cadence invested early in this space working closely with several leading customers.With TSMC we collaborated on the Test Vehicle, implying 3D-IC technologies including two silicon VS to integrate an SoC and embedded DRAM on the silicon interposer. Through our continuous investment in R&D and ecosystem development, we intend to remain well positioned to capitalize on this major shift in semiconductor and manufacturing. Next let us look at the SOC realization. Expanding our design IP business is a priority for Cadence. Martin Lund joined Cadence in March to lead our SoC realization group. Martin joined us from Broadcom where he served for 12 years, most recently as Senior Vice President and General Manager for their Network Switching Business. The addition of Martin further strengthened my integrated management team.
