The MIPI M-PHY is a serial communication protocol for use in mobile systems where performance, power, and efficiency are key criteria. It is the foundation for several upper layer protocols which manage complex data transfer functions. Every protocol is optimized for its particular purpose, such as data storage, data transfer, display, camera, memory sharing, and radio interface.
This article from Cadence outlines how to effectively verify the MIPI protocols that allow designers to more easily adapt to evolving system and application requirements.
Find out why T&VS plays a key role in supporting the mobile ecosystem by developing high-quality, interoperable MIPI IP solutions that enable designers to deploy new features into their next-generation mobile devices.
MIPI UniPro is a recent addition to mobile chip-to-chip interconnects technology. This article from Synopsys outlines the MIPI UniPro benefits and their verification challenges to meet the requirements of mobile applications by describing the three major differentiating features identified below:
- Achieving Low power consumption through Power mode changes and hibernation
- Flexibility in chip-to-chip lane routing through Physical Lane mapping
- Enhanced QoS through CPort arbitration & Data link layer pre-emption
T&VS helped a leading smartphone manufacturer with the verification of its MPHY Anlaog IP. The scope of the activity was to model a MIPI MPHY analog IP using Verilog-AMS with real and to verify the model using a UVM-MS based testbench environment.

TVS, a contributor member of the MIPI Alliance, has developed a diverse portfolio of MIPI Verification IPs (VIPs) which cater to multiple segments of the mobile market. TVS MIPI VIPs are proven in different development environments and are easily customizable for additional customer requirements.
TVS has established a track record as a well-known supplier of MIPI VIPs with some of the major milestones being:
The Verification IP (VIP) supplied by TVS follows a well-defined development process that starts with a feature extraction based on the interface specification from the MIPI Alliance. Not only does this provide a common start point with the client but importantly, an independent development of the VIP. All the VIP deliverables are also linked to the specification through the feature extraction, thus making it easier for users to understand the objectives of the VIP.
TVS has extensive experience in VIP development. With a VIP suite that includes VIPs for Networking, ARM-based protocols, MIPI, Memory & Storage and Universal Serial IO, TVS specializes in providing off the shelf VIP components that can be easily integrated into customer SoC Verification environments at block level and SoC level.

In the mobile world, fast memory bandwidth is not only defining processing speed, it is also defining screen resolution. LPDDR4 combines high data throughput with power efficient operation for smartphones and tablets. No wonder smartphone makers are racing to adopt LPDDR4. In fact, as per this global Forecast of DRAM market revenue table, 2015 will be the turnaround point, and the first year where LPDDRn related revenue will pass DDRn.
If your organization doesn’t have a strategy in place to verify LPDDR4, then TVS might have the solution. The TVS LPDDR4 VIP (offered as part of the asureVIP™ suite) UVM support allows reusability, fully configurable, coverage driven verification at both IP or SOC level verification. The UVM VIP has extensive constrained-random stimuli generation capabilities, configurable monitors and checks to ensure protocol compliance for Host as wells as Peripherals. Pre-defined coverage bins enable easier extension and coverage collection.
TVS recently joined the MIPI® alliance and the TVS MIPI VIP suite, offered as part of its asureVIP portfolio, continues to expand. The company is also working closely with a number of customers to develop new VIP or to update existing VIP to reflect new MIPI Alliance standards or new versions of existing standards. Potential clients can be confident in the quality of TVS VIP through evaluation of existing VIP.
