Improved analysis, modeling, characterization and correlation methods of multi-protocol high-speed transceivers that utilize T-coil to enhance the transmitter and receiver bandwidth, transmitter FIR filters and receiver CTLE and DFE equalizers is presented. The key circuit blocks are measured and modeled using IBIS-AMI models and the overall system performance including the eye diagrams, BER curves are well correlated to on-die measurements. The paper discuss the procedure taken to model, measure, and verify the high-speed transceivers meet the standard specifications such as return loss, jitter tolerance, BER and convergence of the adaptation equalizers and CDR to optimize the margins for various channels.

As an industry, if real progress is to be made towards the level of computing that the future mandates, then the way computing problems are attacked must change. The von Neumann execution model has and will continue to serve us well, but additional techniques must be brought to bear.
The next logical focus area is data—how it is accessed, and how it is transformed into real information—that leads to newer solutions. No longer can all of memory simply continue to be an element that holds the program commands and data during execution. Memory must become an active part of the solution, rather than a necessary evil.
The first step in what is likely to be a protracted journey is to provide a vehicle that allows it to be exploited independently of the CPU. Rambus is doing just that through the creation of their Smart Data Acceleration (SDA) Research Program.
Challenges and Solutions for Future Main Memory

DDR3 SDRAM is used in many computing systems today and offers data rates of up to 1600Mbps. To achieve performance levels beyond DDR3, future main memory subsystems must attain faster data rates while maintaining low power, high access efficiency and competitive cost. This whitepaper will outline some of the key challenges facing next generation main memory and the Rambus innovations that can be applied to advance the main memory roadmap.Use Cases: Personalization
Related to the inherent complexities and costs associated with building a brand new chip, fabless chip manufacturers are under constant pressure to improve operating efficiencies while, at the same time, satisfying OEM customer requirements. As such, large OEM customers requesting personalization, customer specific data preparation and feature customization of standard parts challenge the chipmakers ability to minimize inventory overhead and improve operating efficiencies.
Customer specific personalization services may be accomplished with a high degree of visibility and audit tracking controls that are secured by the CryptoManager solution for each step in the manufacturing supply chain.
For example (see Figure 1), if three OEM customers of a SoC manufacturer each request different feature configurations and/or data preparations for a standard SoC product, the SoC manufacturer needs to figure out how to support three customerspecific part types without creating three different SKUs.
Device personalization creates complexity in manufacturing and in inventory management. With multiple SKUs for standard products, managing inventory for each step requires accurate forecasts and discrepancies can result in wasted silicon or delays in fulfilling orders (see Figure 2)
In this case, pushing the personalization processing step to the end of the manufacturing flow just prior to or, in some cases after delivery to the customer, mitigates the impact on inventory and operations (See 3).
Use Cases: Secure Key Provisioning
With mobile devices housing more and more sensitive data that is utilized in a wide variety of applications, chip and device companies must meet the complex security requirements for each potential use case or capability. Most security measures require the injection of secret identity data and cryptographic keys. Currently, cryptographic keys are provisioned in the open without encryption on test equipment which is operated by third party contract manufacturers. These current provisioning methods expose chip manufacturers to liability and risks for any security breach that occurs within their supply chain.
Utilizing the CryptoManager Root of Trust hardware IP Core, SoC architects have a built-in design for the secure provisioning of cryptographic keys during chip manufacturing. For OEM device manufacturing, this feature also enables remote secure key provisioning at the ODM (Original Device Manufacturer).
