Foundation IP For 7nm FinFETs: Design And Implementation
By Synopsys - 13 Apr, 2016 - Comments: 0

Learn about the challenges of IP design and implementation for 7nm FinFETs. Along with the performance and area benefits that the node brings, designers must understand the significant technical challenges stemming from increasing variability associated with tighter pitches and more complex lithography steps. Design for variability and reliability considerations will require comprehensive model... » read more

New Memory Approaches And Issues
By Ed Sperling - 14 Mar, 2016 - Comments: 1

New memory types and approaches are being developed and tested as DRAM and Moore's Law both run out of steam, adding greatly to the confusion of what comes next and how that will affect chip designs. What fits where in the memory hierarchy is becoming less clear as the semiconductor industry grapples with these changes. New architectures, such as [getkc id="202" kc_name="fan-outs"] and [getk... » read more

Mixed-Signal Design Powers Ahead
By Ann Mutschler - 10 Mar, 2016 - Comments: 1

Mixed-signal devices are at the heart of many advanced systems today because of the need to interact with the outside world, but designing and verifying these systems is getting harder. There are several reasons for this. First, almost all of these devices now have to be lower power than in the past, and in the analog space it's not as simple as just dialing down part of a block. Second, it ... » read more

Complete Systems Modeling And Simulation For Complex Product Development
By Ansys - 24 Feb, 2016 - Comments: 0

As products in the marketplace incorporate more and more complexity, the product design process must keep pace to ensure safe, efficient and reliable integration of complicated systems, subsystems and components. Few products today involve a mere single physics; most encompass multidisciplinary behaviors and interactions (with subsequent, sometimes unpredictable, cause and effect). Though simul... » read more

Who’s Profiting From Complexity
By Ed Sperling - 21 Dec, 2015 - Comments: 0

Tool vendors' profits increasingly are coming from segments that performed relatively poorly in the past, reflecting both a rise in complexity in designing chips and big improvements in the tools themselves. The impacts of power, memory congestion, advanced-node effects such as process variation, [getkc id="160" kc_name="electromigration"] and RC delay in [getkc id="36" kc_name="interconnect... » read more

How To Model Cars
By Ann Mutschler - 03 Dec, 2015 - Comments: 1

The most technologically advanced and comprehensive consumer product in the world today is not the smartphone. It's the automobile. This is easier to see once the hood is up and you can take a peek around. Today’s cars contain sophisticated motion systems, crash safety systems, climate control systems, driver assistance, and infotainment, to name a few. In semiconductor design, one of the ... » read more

Outbound Power Management
By Srikanth Jadcherla - 15 Oct, 2015 - Comments: 0

Many years ago when I first suggested that we should do platform-level power instead of focusing on the CPU, I was considered somewhat of a heretic. Yet, within 10 to 15 years of that recommendation, most of the platforms around us have moved to that method using operating system functions to keep track of the overall power, battery life, etc. As we move into the era of billions of connected de... » read more

IP Integration Challenges Increase
By Ed Sperling - 16 Jun, 2015 - Comments: 0

Semiconductor Engineering sat down with Chris Rowen, CTO of [getentity id="22032" e_name="Cadence"]'s IP group; Rob Aitken, an [getentity id="22186" comment="ARM"] fellow; Patrick Soheili, vice president of product management and corporate development at [getentity id="22242" e_name="eSilicon"]; Navraj Nandra, senior director of marketing for DesignWare analog and mixed-signal IP at [getentity ... » read more

What Is Functional Accuracy?
By Ann Mutschler - 26 Mar, 2015 - Comments: 0

What it means to be functionally accurate in the context of [getkc id="104" kc_name="virtual platforms"] varies greatly, depending upon whom you ask and even when you ask them. But that doesn’t mean that functional accuracy isn’t useful. Jon McDonald, technical marketing engineer for the design and creation business at [getentity id="22017" e_name="Mentor Graphics"], expects to see a lot... » read more

How Many Levels Of Abstraction Are Needed?
By Jon McDonald - 23 Oct, 2014 - Comments: 0

Recently I was having a conversation with a user who was creating cycle accurate SystemC models. My initial thought was, "Why would this be necessary?" Through the course of discussions I realized that he did have a design questions that required that level of accuracy and the simulation performance trade-offs were appropriate for his needs. His cycle accurate SystemC models were running at abo... » read more
