User Feedback

"Wipro has been consistently enabling semiconductor companies to reduce verification time and increase coverage parameters through its next-generation frameworks and market-proven end-to-end verification services. Our partnership with Cadence has played an instrumental role in fulfilling the IP verification needs of our customers. We chose PCIe Gen3 VIP along with TripleCheck by Cadence to achieve a comprehensive solution that gives us the fastest path to IP verification closure."
- A. Vasudevan, VP Semiconductor and Systems, Wipro

"We’ve determined that 90% of the risk is in the chip’s interfaces. If we design the interfaces incorrectly, it doesn’t matter if we get the rest of the chip right. This is especially true with PCI Express since it’s such a complex protocol. The bottom line for us is that the choice we made to go with proven IP that’s easy to get up and running is really just good, solid common sense. "
