Can a hierarchical Test flow be used on a flat design?

Can a hierarchical Test flow be used on a flat design?
by Tom Simon on 08-15-2019 at 10:00 am

It is pretty common for physical layout to work from a flattened hierarchy for blocks or even full chips, even though the front-end design starts with a hierarchical representation. This was not always the case. Way back when, the physical layout matched the logical hierarchy during the design process. Of course, this led to all… Read More

It’s easy to imagine that the main impetus for automotive electronics safety standards like ISO 26262 is the emergence of autonomous driving technology. However, even cars that do not offer this capability rely heavily on electronics for many critical systems. These include engine control, braking, crash sensors, and stability… Read More


Hierarchical RTL Based ATPG for an ARM A75 Based SOC

Two central concepts have led to the growth of our ability to manage and implement larger and larger designs: hierarchy and higher levels of abstraction. Without these two approaches the enormous designs we are seeing in SOCs would not be possible. Hierarchy in particular allows the reuse of component blocks, such as CPU cores.… Read More

It is an indictment of our irrationality that our cars are now more health-conscious than we Image Removedare. Increasingly safety-conscious readings of the ISO26262 standard now encourage that safety-critical electronics (anti-lock braking control for example) automatically self-test, not just at power-on but repeatedly… Read More

Introducing on-chip test circuitry has become a necessary criteria for an ASIC’s post manufacture testability. The test circuitry is usually referred as DFT (Design-for-Test) circuit. A typical methodology for introducing DFT circuit in a design is to replace usual flip-flops with special types of flip-flops called ‘sc… Read More

In a semiconductor design, keeping the design testable with high test coverage has always been a requirement. However with shrinking technology nodes and large, dense SoC designs and complex logic structures, while it has become mandatory to reach close to 100% test coverage, it’s extremely difficult to cope with the explosion… Read More


Early Test –> Less Expensive, Better Health, Faster Closure

Early Test –> Less Expensive, Better Health, Faster Closure

Image Removed
I am talking about the health of electronic and semiconductor design, which if made sound at RTL stage, can set it right for the rest of the design cycle for faster closure and also at lesser cost. Last week was the week of ITC(International Test Conference) for the Semiconductor and EDA community. I was looking forward… Read More

Image RemovedIn the embedded world that drives much of today’s ASIC innovation, there is no bigger name than ARM. Not to enter the ARM vs. Intel fray, but it’s no exaggeration to say that ARM’s impact on SoCs is as great as Intel’s on the PC. Few cutting edge SoCs are coming to market that do not include some… Read More
