The History Of CMOS


Since CMOS has been around for about 50 years, a comprehensive history would be a book. This blog focuses on what I consider the major transitions. NMOS Before CMOS, there was NMOS (also PMOS, but I have no direct experience with that). An NMOS gate consisted of a network of N-transistors between the output and Vss, and a resistor (actually a transistor with an implant) between the output and... » read more

Blog Review: May 24


Siemens' Patrick McGoff finds that designers have not had easy tools to address solderability, leaving a critical part of the manufacturing success of a PCB to the component engineer or the contract manufacturer, and points to manufacturing-driven design as a way to avoid quality issues later. Cadence's Rich Chang finds that effective UPF low-power verification and debug involves more than o... » read more

Celsius EC Solver


The Cadence Celsius EC Solver is electronics cooling simulation software for accurate and fast analysis of the thermal performance of electronic systems. It enables electronic system designers to accurately address the most challenging thermal/electronics cooling issues today. The Celsius EC Solver utilizes a powerful computational engine and meshing technology that enables designers to model a... » read more

Chips Getting More Secure, But Not Quickly Enough


Experts at the Table: Semiconductor Engineering sat down to talk about the impact of heterogeneous integration, more advanced RISC-V designs, and a growing awareness of security threats, with Mike Borza, Synopsys scientist; John Hallman, product manager for trust and security at Siemens EDA; Pete Hardee, group director for product management at Cadence; Paul Karazuba, vice president of marketin... » read more

Blog Review: May 17


Synopsys' Dana Neustadter examines the key industries driving Ethernet security, challenges to securing Ethernet networks, and the MACsec protocol that guards against network data breaches by encrypting data traffic between Ethernet-connected devices. Siemens' Stephen Chavez points to the improvements gained from design reuse in PCB design but warns that inefficient processes for managing an... » read more

Machine Vision Plus AI/ML Adds Vast New Opportunities


Traditional technology companies and startups are racing to combine machine vision with AI/ML, enabling it to "see" far more than just pixel data from sensors, and opening up new opportunities across a wide swath of applications. In recent years, startups have been able to raise billions of dollars as new MV ideas come to light in markets ranging from transportation and manufacturing to heal... » read more

Holistic Power Reduction


The power consumption of a device is influenced by every stage of the design, development, and implementation process, but identifying opportunities to save power no longer can be just about making hardware more efficient. Tools and methodologies are in place for most of the power-saving opportunities, from RTL down through implementation, and portions of the semiconductor industry already a... » read more

Making Tradeoffs With AI/ML/DL


Machine learning, deep learning, and AI increasingly are being used in chip design, and they are being used to design chips that are optimized for ML/DL/AI. The challenge is understanding the tradeoffs on both sides, both of which are becoming increasingly complex and intertwined. On the design side, machine learning has been viewed as just another tool in the design team's toolbox. That's s... » read more

Rethinking Engineering Education In The U.S.


The CHIPS Act, as well as the ongoing need for talent, is causing both industry and academia in America to rethink engineering education, resulting in new approaches and stronger partnerships. As an example, Arizona State University (ASU) now has a Secure, Trusted, and Assured Microelectronics Center (STAM). The center offers an interdisciplinary approach to learning secure and trusted semic... » read more

High-Fidelity CFD Mesh Generation With Voronoi Diagram


We are attuned to the fact that the law of nature, or nature’s rule, drives various scientific phenomena. Humans often replicate naturally occurring phenomena to achieve a desirable outcome, similar to how scientists mimic photosynthesis to generate energy. Comparable is the case with Voronoi geometries. These geometries are widely seen in beehives, the structure of sponges, rock fragmentati... » read more
