There is an adage that says that quality is not something that can be slapped on at the end of the design or manufacturing process. Ensuring quality requires careful thought throughout development and production. Arguably this adage is more applicable to the topic of Design for Test (DFT) than almost any other area of IC development… Read More

It requires lateral thinking in bringing new innovation into conventional solutions to age-old hard problems. While the core logic design has evolved adding multiple functionalities onto a chip, now called SoC, the structural composition of DFT (Design for Testability) has remained more or less same based on XOR-based compression… 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 ‘scan… Read More

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


How to Assure Quality of Power and SI Verification?

How to Assure Quality of Power and SI Verification?
by Pawan Fangaria on 12-08-2013 at 10:05 am

As power has become one of the most important criteria in semiconductor design today, I was wondering whether there is a standard set for the power verification for an overall chip. We do have formats evolved like CPF and UPF and there are tools available to check power and signal integrity (SI), however I don’t see a standard objective… Read More


It Takes a Village: Mentor and ARM Team Up on Test

It Takes a Village: Mentor and ARM Team Up on Test
by Beth Martin on 07-18-2012 at 5:01 pm

Benjamin Franklin, “I didn’t fail the test, I just found 100 ways to do it wrong.” I was reminded of this line during a joint Mentor-ARM seminar yesterday about testing ARM cores and memories. The complexity of testing modern SoC designs at advanced nodes, with multiple integrated ARM cores and other IP, opens up plenty of room for… Read More
