Backchannel Modeling And Simulation Using Recent Enhancements To The IBIS Standard


Recent enhancements to the upcoming IBIS standard now support backchannel training, enabling IBIS-AMI models to emulate this real-world SerDes behavior. AMI modelers now can incorporate backchannel algorithms into their IBIS-AMI models, automating the optimization of transmitter and receiver equalization settings in the same manner as their actual SerDes hardware devices. This saves system desi... » read more

Functional Safety Methodologies For Automotive Applications


Safety-critical automotive applications have stringent demands for functional safety and reliability. Traditionally, functional safety requirements have been managed by car manufacturers and system providers. However, with the increasing complexity of electronics involved, the responsibility of addressing functional safety is now propagating through the supply chain to semiconductor companies a... » read more

Meeting The Challenges Of The 2018 National Defense Strategy


In Secretary of Defense James Mattis’ Summary of the 2018 National Defense Strategy: Sharpening the American Military’s Competitive Edge, he provides a critical framework for driving “urgent change at significant scale.” This paper describes the role that Cadence can play in assisting the nation and its partners in achieving that urgency and scale of change called for in the vision and ... » read more

Signal Integrity Methodology For Double-Digit Multi-Gigabit Interfaces


As data rates for serial link interfaces such as PCI Express (PCIe) Gen 4 move into the double digits, device modeling, interconnect modeling, and analysis methodologies must continue to evolve to address the shrinking design margins and increasingly challenging compliance criteria facing today’s engineers. To mitigate risk and optimize designs, it is critical to move analysis as far upstream... » read more

Pattern-Based Analytics To Estimate And Track Yield Risk Of Designs Down To 7nm


Topological pattern-based methods for analyzing IC physical design complexity and scoring resulting patterns to identify risky patterns have emerged as powerful tools for identifying important trends and comparing different designs. In this paper, previous work is extended to include analysis of layouts designed for the 7nm technology generation. A comparison of pattern complexity trends with r... » read more

Methodology For Analyzing And Quantifying Design Style Changes And Complexity Using Topological Patterns


In order to maximize yield, IC design companies spend a lot of effort to analyze what types of design styles are needed and used in their layouts (standard cells, macros, routing layers, and so forth). This paper introduces a novel methodology for full chip high performance topological pattern analysis and the applications of this methodology towards analyzing design styles in order to quanti... » read more

Three Things You Need To Know To Use The Accellera PSS


Three primary considerations for adopting the Accellera Portable Stimulus Standard (PSS) are understanding the following: the value and relevance of this standard; the fundamental concepts of PSS modeling, including building blocks, process, and mindset; and PSS portability and how these scenarios can be applied to a specific platform. In this paper, we explore these three topics. To read mo... » read more

Efficient Verification Of Mixed-Signal SerDes IP Using UVM


Interface IP is an integral part of systems-on-chips (SoC) that include mobile, automotive, or networking applications and are primarily used for transmitting data over a physical medium between a host and device. The mixed-signal nature of the IP makes verification a challenging task, requiring special considerations for digital and analog sections. This paper describes a robust mixed-signal v... » read more

Modeling Of The Electrical Performance Of The Power And Ground Supply For A PC Microprocessor On A Card


The electrical characteristics of the power and ground supply of a PC microprocessor packaged in a Ball Grid Array (BGA) package mounted on a card are studied by dynamic electromagnetic field analysis. The effects of decoupling capacitors of different types and at different locations are investigated to achieve the objectives of low power and ground impedance and no or insignificant resonances ... » read more
