"DFY and DFR are more important than DFT"

چکیده
The purpose of testing a circuit is to verify that it functionally matches its ideal behavior. If the behavior is not what is anticipated, it is considered failing. If the failing behavior is a result of a defective design, e.g. a “bug”, a serious re-design effort would be undertaken. This re-design is based upon knowledge of typical circuit behavior and re-design encompasses using a broad spectrum of electrical modeling. However, this only looks into one aspect of a circuit: the electrical representation. This effort does not necessarily explore the physical manifestation of the components used to create the circuit and their susceptibility to failure.

Design for Yield and Reliability is MORE Important Than DFT
Introduction Most IC design engineers today are at the same stage when considering Design for Yield (DFY) and Design for Reliability (DFR) as they were when considering Design for Test (DFT) 20 years ago. Most engineers poorly understand them, there are few EDA tools to help them, and there is no consensus about whether it is even worthwhile. It is just one more Design for X that they don’t hav...
متن کاملIt Makes Sense to Combine DFT and DFR/DFY
Historically, it has been common to treat design for testability (DFT) independently of design for reliability (DFR) and design for yield (DFY). DFT is viewed as an add-on to the standard design process — something that happens in parallel with design, but off the main path. DFR is seldom considered at all during the design process, with the exception of ESD circuitry, another add-on late in ch...
متن کاملDFT, DFY, and DFR; Which One(s) Do You Worry About?
Lately our vernacular has included a growing number of DFx terms. DFT (Design for Test), DFY (Design for Yield), and DFR (Design for Reliability) have become fairly common and useful terms along with a few other DFx terms such as DFM (Design for Manufacturability) and DFP (Design for Profit). The last term has a bit of a capitalistic slant. One could say that we have gone too far with all these...

vision of its delivery of management leader naturally tends to disappear upon the product to the customers, since focus continually shifts to the next test coverage to insure that defective product is not shipped will also be overlookedunderestimated by such managers. Design techniques in the layout that contribute to greater yield will not likely be on their radar screen as their focus will be...
متن کاملThe Duffy antigen modifies systemic and local tissue chemokine responses following lipopolysaccharide stimulation.
The Duffy blood group Ag (dfy) binds selective CXC and CC chemokines at high affinity and is expressed on erythrocytes and endothelial cells. However, it does not transmit a signal via G proteins, as occurs with other seven-transmembrane receptors. We hypothesized that dfy functions as a chemokine reservoir and regulates inflammation by altering soluble chemokine concentrations in the blood and...
