A Reliable I/O Ring For A Reliable SoC


What is an input/output (I/O) ring, and why should I care about it? If you’re a system-on-chip (SoC) designer, you had better know the answer to that question. SoCs are the darlings of the semiconductor industry—they combine all the typical functionality of a computer (central processing unit (CPU), memory, input/output (I/O) ports, and storage) on a single chip. They’re particularly popu... » read more

Wrestling With High-Speed SerDes


SerDes has emerged as the primary solution in chips where there is a need for fast data movement and limited I/O, but this technology is becoming significantly more challenging to work with as speeds continue to rise to offset the massive increase in data. A Serializer/Deserializer is used to convert parallel data into serial data, allowing designers to speed up data communication without h... » read more

Speed Up P2P Resistance Debugging With Selective Highlighting


Point-to-point (P2P) resistance simulation calculates the effective parasitic resistance from one or more specified points (sources) to another set of points (sinks) on an integrated circuit (IC) layout. The results of these simulations are a key component in the verification of the robustness and reliability of IC layout interconnect—designers must have this information to accurately perform... » read more

Week In Review: Manufacturing, Test


Trade wars The trade war between the United States and China is escalating and it is here to stay. Victor Davis Hanson, a senior fellow at think tank Hoover Institution, said the United States is at a crossroads with China. It could define America’s security and the international order for decades to come. Here’s the latest blog on trade tensions between the U.S. and China. “Tensions ... » read more

The Long And Detailed Road To Automotive Compliance


Compliance with automotive safety requirements is slowing down both innovation and participation by a flurry of startups as the whole ecosystem struggles to bring autonomous vehicles to reality. This is particularly onerous for chipmakers, which face a high bar for IC integrity and reliability. They must meet specifications and be free of design errors. Improper behavior in corner-case s... » read more

A Comprehensive Approach To System-Level ESD


The performance and reliability of an electronics system largely depend on the system’s immunity from an electrostatic discharge (ESD) event. Because the components, custom chips and package come from various sources — and often from different companies — they are usually designed by separate teams working in silos and in accordance with predefined margins. The ESD Association estimates t... » read more

Design Rule Complexity Rising


Variation, edge placement error, and a variety of other issues at new process geometries are forcing chipmakers and EDA vendors to confront a growing volume of increasingly complex, and sometimes interconnected design rules to ensure chips are manufacturable. The number of rules has increased to the point where it's impossible to manually keep track of all of them, and that has led to new pr... » 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
