Extrapolating the trends from last 20 years to the next ten suggests that we will be implementing a trillion transistors or more by 2020. At 20nm, with the chip sizes touching billions of transistors, the age old problem of how to implement a design in the most efficient manner remains unanswered. … Read More
My first chip design at Intel was a DRAM and we had a 5% yield problem caused by electromigration issues, yes, you can have EM issues even with 6um NMOS technology. We had lots of questions but precious few answers on how to pinpoint and eliminate the source of yield loss. Fortunately, with the next generation of DRAM quickly introduced… Read More
Although design for manufacturing (DFM) tools and techniques have been around for several nodes, a lot of designers remain skeptical about their actual value, especially since many products still make it successfully to market without the use of DFM.… Read More
This year’s SPIE Advanced Lithography is loaded with interesting keynotes and sessions. To help me narrow down what to see, I spoke with John Sturtevant. John is co-chair of the Design for Manufacturability through Design-Process Integration conference, and the director for technical marketing for RET products at Mentor Graphics.… Read More
Consumer electronics is a new driver in our global semiconductor economy as we enjoy using Smart Phones, Tablets and Ultra Books. The challenge of designing and then verifying the electronic systems to meet the market windows is a daunting one. Instead of starting with a blank sheet for a new product, most electronic design companies… Read More
For the greater good of the semiconductor ecosystem, SemiWiki and Mentor Graphics present SemiWiki Seminars, a free seminar and software demonstration series addressing the latest innovations in IC design. SemiWiki Seminars discuss interesting new challenges and potential solutions aimed at increased circuit density … Read More
Hierarchy is used in IC designs at many abstraction levels to help describe a design in a compact format:
But the question and focus for this blog is, “What is a hierarchical SPICE Circuit Simulator?”… Read More
In my last corporate EDA job I had customers in Korea that were evaluating a new circuit simulator and getting strange results. When I asked, “Could you send me your test case?” the reply was always, “No, we cannot let any of our IC design data leave the building because of security concerns.”… Read More
Joe Sawicki is the VP and General Manager at Mentor Graphics for the Design-to-Silicon Division where the Calibre product line is developed. We met today in Wilsonville, Oregon to review the challenges in IC design, processing and manufacturing.… Read More
Preventing electrical circuit failure is a growing concern for IC designers today. Certain types of failures such as electrostatic discharge (ESD) events, have well established best practices and design rules that circuit designers should be following. Other issues have emerged more recently, such as how to check circuits… Read More
