STMicroelectronics fuse our encounter digital and virtual custom analog platforms to complete a 20 nanometer mix signal test chip. Our Encounter and virtual platforms received Phase I certification for TSMC 20 nanometer technology. We collaborated with Samsung on the 20 nanometer methodology that includes double patterning technology. The number of 20 nanometer engagement with key customers is growing in every region, overall we are working with 16 different customers at 20 nanometer with more than 30 designs in progress or complete using encounter. At 40 nanometer process note we had joint projects underway and are working on test chips. The increased complexity of modern SoC is driving demand for our advanced verification solutions.
In Q2, we closed a significant order for our incisive verification platform with a top 10 semi-conductor company. I have some exciting progress to report in the physical verification area. As a result on going collaboration TSMC is now making DRC and LDS Root/x (ph) available for our physical verification system product at a 28 and 20 nanometer nodes. This is yet another proof point that our investment at 20 nanometer node is producing competitive products and creating new opportunities for us.
Our acquisition of Azuro and its unique breakthrough, clock concurrent optimization now integrated into our encounter digital solution. It enables customer to materially improve the power, performance and area of the design especially those containing ARM core.
This creates opportunities for us to expand our digital footprint with some customers. (Inaudible) was one successful customer story during the quarter. We are working with a number of major customers including Renesas, who are achieving outstanding results using encounter with Azuro technology built-in.Next let us look at SoC realization, our design IP business is growing rapidly. The DDR5 and PCI Express Control, controller product lines both have record bookings for the quarter. We are aggressively expanding our product line as we strive to have products ready for new protocols when customers meet them. Read the rest of this transcript for free on seekingalpha.com
