Typically, there is an existential rift between the on-chip access requirements for test and the need for security in SoCs. Using traditional deterministic scan techniques has meant opening up full read and write access to the flops in a design through the scan chains. Having this kind of access easily defeats the best designed… Read More
You may have seen a recent announcement from Mentor, a Siemens business, regarding the use of their Tessent DFT software by Ambarella for automotive applications. The announcement is a good example of how Mentor works with their customers to assure design success. On the surface the announcement comes across as a nice block and… Read More
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 is an indictment of our irrationality that our cars are now more health-conscious than we are. 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 as the car… 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
While focus of the semiconductor industry has shifted to DACin this week and unfortunately I couldn’t attend due to some of my management exams, in my spare time I was browsing through some of the webpages of Cadenceto check their new offerings (although they have a great list of items to showcase at DAC) and to my pleasure I came across… Read More
At the ITC test conference in early September, Mentor made three announcements. ITC is a big event for Mentor’s test group, and where they usually roll out their new tools and capabilities. The indefatigable Steve Pateras was captured on film describing them.
I’ve summarize Mentor’s three announcements and added… Read More
