The Circle Of Test And EDA Is Complete
By Brian Bailey - 22 May, 2014 - Comments: 1

For those of you who were around and involved with EDA back in the early ’80s, you may remember that chip design was not the focus. It was the board that received most of the attention. Chips were small and did not require much in the way of functional verification. [getkc id="29" kc_name="Synthesis"] had not been invented and so gate-level design was where everything happened, and much of th... » read more

How Much Testing Is Enough?
By Mark LaPedus - 15 May, 2014 - Comments: 1

As chipmakers move towards finer geometries, IC designs are obviously becoming more complex and expensive. Given the enormous risks involved, chipmakers must ensure the quality of the parts before they go out the door. And as part of quality assurance process, that requires a sound test strategy. But for years, IC makers have faced the same dilemma. On one hand, they want a stringent test me... » read more

Improving Yield Of 2.5D Designs
By Ann Mutschler - 18 Apr, 2014 - Comments: 0

While progress is being made on the packaging side of 2.5D design, more needs to be resolved when it comes to improving yields. Proponents of 2.5D present compelling benefits. Arif Rahman, a product architect at Altera, noted that the industry trend of silicon convergence is leading to multiple technologies being integrated into single-chip solutions. “2.5D/3D integration has multiple adva... » read more

DSP-Based Testing
By Various Writers - 16 Apr, 2014 - Comments: 0

ADC and DAC are the most typical mixed signal devices. In mixed signal testing, analog stimulus signal for an ADC is generated by an arbitrary waveform generator (AWG) which employs a D/A converter inside, and an analog signal out of a DAC is measured by a digitizer or a sampler which employs an A/D converter inside. The stimulus signals for these devices are created using mathematical method, ... » read more

Blog Review: April 2

Mentor’s Nazita Saye compares roadway roundabouts to networked systems. One roundabout works fine, but add in a bunch of them and you have a massive traffic jam. How many roundabouts are in your design? Cadence’s Richard Goering interviews Stan Kroliskoski, chair of the IEEE Design Automation Standards Committee, about four working groups on EDA standards and what’s ahead. Speaking ... » read more

Enabling Test Portability With Graphs
By Ann Mutschler - 20 Mar, 2014 - Comments: 0

Is it time to move up again? When it comes to test portability between simulation, emulation, prototypes and silicon, as well as an easier way to create a test structure, the answer appears to be a resounding ‘Yes.’ Looking at these activities from a higher level of abstraction and using a graph-based approach should allow automation where there has been none previously, and could allow val... » read more

Test Challenges Rising For Mobile Devices
By Mark LaPedus - 20 Mar, 2014 - Comments: 0

Smartphone and tablets continue to advance at a dizzying pace. On the component side alone, the latest mobile devices are moving towards 64-bit application processors, multi-mode RF front-ends, higher-end cameras and flashy LCD screens. Some systems even boast fingerprint scanners and heart rate sensors. But an obvious part of the system continues to lag behind the curve—battery life. In r... » read more

More Pain In More Places
By Ed Sperling - 14 Mar, 2014 - Comments: 2

Pain is nothing new in to the semiconductor industry. In fact, the pain of getting complex designs completed on budget, and finding the bugs in those designs, has been responsible for decades of continuous growth in EDA, IP, test, packaging, and foundries. But going forward there is change afoot in every segment of the flow from architecture to design to layout to verification to manufacturi... » read more
