- 28. Customer Testimonial "Our team at Mixel used Arrow Devices' MIPI MPHY VIP to validate our Type-I MPHY design. The VIP is easy to use and provides complete comprehensive test coverage for MPHY. With approximately ~300 tests (directed compliance as well as constrained random tests), the VIP helped us catch tricky corner case issues in our design. After verifying our design with Arrow Devices VIP, we are much more confident about our MPHY design to be risk free and standard compliant. We found Arrow Devices team very helpful, committed and, easy to work with. It provided excellent support throughout the verification phase.Overall, working with Arrow Devices has been very good and useful experience." Anupama Dikhit, Senior Design Engineer, Mixel
