ISO 26262-Certified Solution for Testing of Safety-Critical Automotive ICs
ISO 26262-Certified Solution for Testing of Safety-Critical Automotive ICs Anti-lock braking systems, air bags, traction control, and electronic stability control are just a few examples of typical safety systems in current production cars. Next-generation safety systems, known as Advanced Driver Assistance Systems, or ADAS, are setting up the path for semi- and fully autonomous cars of the near future. Some ADAS technology uses a combination of cameras and radar to sense, identify, and alert drivers of potential collision with other vehicles, pedestrians, or other objects, and may, in some cases, proactively steer or brake the car to avoid collision to minimize injury or damage. Other types of ADAS technology can automate common driving operations with the objective of improving safety, such as lane changing or traffic jam assistance, thus providing semi-autonomous driving options.

IC Compiler II Multi-Level Physical Hierarchy Floorplanning
Large, complex SoC designs require hierarchical layout methodologies that span multiple levels of physical hierarchy. Many EDA tools only handle two levels of physical hierarchy at a given time resulting in longer layout schedules that are risky at best. This paper presents the need for multi-level physical hierarchy floorplanning, the challenges inherent with this style when using tools limited to two levels of hierarchy, and discusses how IC Compiler II addresses these challenges.

Realizing Advanced P&R Design Utilizing Established Process Nodes
Despite the high mindshare garnered by the latest developments at 16nm and 10nm, the fact is that the majority of designs taped out today are at 45nm and above. It is clearly the time to disassociate the term "advanced" from "technology node". Advanced designs are occurring at both established process nodes and at emerging process nodes. Today, advanced design should be considered process node independent. This paper takes an i-ndepth look at advanced place and route design using established process nodes.

Physical Verification of FinFETs and Fully Depleted SOI
It has come to be broadly accepted in the semiconductor industry that short-channel effects severely limit bulk planar transistor performance, and alternative device structures will necessarily have to be adopted if we are to shrink process geometries below 20nm. This paper explores the two major contenders for the new transistor architecture: finFETs and fully depleted silicon-on-insulator.

Realizing Low Power IC Design: It Starts with the Clock Tree
There are numerous techniques to achieve a low-power design and several approaches to structuring the flow. As a starting point, high performance designs require a benchmark proven low-skew, low-insertion delay CTS solution. Correlation to industry standard sign-off engines for accuracy and minimum data format translations are required to achieve fast design closure. The optimal solution includes complete low power capability throughout the design flow. This paper addresses low power design issues and includes technologies and techniques to achieve high performance, low power design goals.

Clock Mesh for Mainstream Designs
By its very nature, even the best conventional clock tree synthesis leaves both performance and variation tolerance potential on the table. Clock mesh offers the designer a means of achieving extreme high performance along with the avoidance of process variation effects. Long known as the clock distribution method for high-end microprocessors, clock mesh also offers significant variation tolerance. Clock mesh use to be an entirely manual, difficult to analyze technology, but new advances in clock mesh automation and analysis now enable it to be considered as a mainstream clock distribution solution.

Advanced Design Challenges Make DFM-Friendly Routing A Must-Have
Timing, area, power, and signal integrity have traditionally been the primary objectives of design technology, and the primary care-abouts for designers and CAD engineers. Increasingly manufacturability and yield have also become critical design objectives, and multiple design-for-manufacturability (DFM) optimization techniques have been added to the design flows. As manufacturability has been a secondary goal, conventional routers have been optimizing for it after timing optimization – the point at which all of the primary design goals have already been met. While this methodology has worked well up to the 65nm technology node, it starts to break down at 45nm and below. This paper talks about the routing challenges at 45nm and below and the need for modern DFM-friendly routing technologies for achieving better manufacturability and higher yield without sacrificing performance.

Realizing a Scalable Hierarchical Design Flow: What’s Needed for Large Designs
Today’s system on a chip (SoC) designs continue to get larger and more complex. Given that consumer products are now the main driver for SoC designs, design teams must deliver chips quickly to capture as much revenue as possible from the latest consumer trend. Flat implementation flows are inefficient in terms of computer system resource requirements and runtimes for large SoC designs. Teams are turning to hierarchical design flows to implement these designs. This paper discusses design exploration and planning in a hierarchical flow for large SoCs and delves into efficient techniques that produce fast turn times and a concurrent physical implementation that enables predictable design convergence.
