Smart Strategies for Efficient Testing of 3D-ICs

Smart Strategies for Efficient Testing of 3D-ICs
by Pawan Fangaria on 02-12-2014 at 6:30 am

3D-IC has a stack of dies connected and packaged together, and therefore needs new testing strategies other than testing a single die. It’s given that a single defective die can render the whole of 3D-IC unusable, so each die in the stack must be completely and perfectly tested before its entry into that stack. Looking at it from a … Read More

Parasitic Debugging in Complex Design – How Easy?

Parasitic Debugging in Complex Design – How Easy?
by Pawan Fangaria on 01-23-2014 at 9:00 am

When we talk about parasitic, we talk about post layout design further expanded in terms of electrical components such as resistances and capacitances. In the semiconductor design environment where multiple parts of a design from different sources are assembled together into highly complex, high density SoC, imagine how complex… Read More


ESD at TSMC: IP Providers Will Need to Use Mentor to Check

ESD at TSMC: IP Providers Will Need to Use Mentor to Check
by Paul McLellan on 01-22-2014 at 1:24 pm

I met with Tom Quan of TSMC and Michael Beuler-Garcia of Mentor last week. Weirdly, Mentor’s newish buildings are the old Avant! buildings where I worked for a few weeks after selling Compass Design Automation to them. Odd sort of déja vu. Historically, TSMC has operated with EDA companies in a fairly structured way: TSMC … Read More


SilabTech Awarded 2013 Best Start-up in India

SilabTech Awarded 2013 Best Start-up in India
by Eric Esteve on 01-20-2014 at 8:32 am

This is obviously great news for SilabTech, and this is the type of news which will change the perception that we (non-Indian) have of the Semiconductor industry in India. About 15-20 years ago, the India Embedded/VLSI industry was perceived as low cost design resource pool, a good place where to implement design center. The hidden… Read More


Managing Heat for System Reliability

Managing Heat for System Reliability
by Pawan Fangaria on 01-17-2014 at 8:30 am

In most of the electronic equipments, semiconductor chips are a major source of heat generation. And in semiconductor designs several hardware and software techniques are being used to contain power dissipation; a major cause for heat. However due to multiple functionality being squeezed into small form factors, we continue… Read More


New Frontiers in Scan Diagnosis

New Frontiers in Scan Diagnosis
by Paul McLellan on 01-03-2014 at 8:10 pm

As we move down into more and more advanced process nodes, the rules of how we test designs are having to change. One big challenge is the requirement to zoom in and fix problems by doing root cause analysis on test data alone, along with the rest of the design data such as detailed layout, optical proximity correction and so on. But without… Read More


Macro Placement Challenges

Macro Placement Challenges
by Paul McLellan on 12-27-2013 at 7:28 pm

One of the challenges of physical design of a modern SoC is that of macro placement. Back when a design just had a few macros then the flooplanning could be handled largely manually. But modern SoCs suffer from a number of problems. A new white paper from Mentor covers Olympus-SOCs features to address these issues:

  • As we move to smaller

Highest Test Quality in Shortest Time – It’s Possible!

Highest Test Quality in Shortest Time – It’s Possible!
by Pawan Fangaria on 12-26-2013 at 10:30 am

Traditionally ATPG (Automatic Test Pattern Generation) and BIST (Built-In-Self-Test) are the two approaches for testing the whole semiconductor design squeezed on an IC; ATPG requires external test equipment and test vectors to test targeted faults, BIST circuit is implemented on chip along with the functional logic of IC.… Read More


Mentor Buys Oasys

Mentor Buys Oasys
by Paul McLellan on 12-14-2013 at 1:24 pm

Mentor is acquiring Oasys, subject to all the usual caveats about shareholder and regulatory approval. The shareholder paperwork went out earlier this week. The common stock is valueless so presumably the price is low (and Mentor historically has not paid high prices for its acquisitions).

So what is going to happen with the technology?… Read More
