Pinpointing Timing Delays in Complex SoCs


Telemetry circuits are becoming a necessity in complex heterogeneous chips and packages to show how these devices are behaving post-production, but fusing together relevant data to identify the sources of problems adds its own set of challenges. In the past, engineering teams could build margin into chips to offset any type of variation. But at advanced nodes and in advanced packages, tolera... » read more

Pinpointing Timing Delays Can Improve Chip Reliability


Growing pressure to improve IC reliability in safety- and mission-critical applications is fueling demand for custom automated test pattern generation (ATPG) to detect small timing delays, and for chip telemetry circuits that can assess timing margin over a chip's lifetime. Knowing the timing margin in signal paths has become an essential component in that reliability. Timing relationships a... » read more

Test Challenges Mount As Demands For Reliability Increase


An emphasis of improving semiconductor quality is beginning to spread well beyond just data centers and automotive applications, where ICs play a role in mission- and safety-critical applications. But this focus on improved reliability is ratcheting up pressure throughout the test community, from lab to fab and into the field, in products where transistor density continues to grow — and wh... » read more

Solution Efficiencies For Dynamic Function eXchange Using Abstract Shells


Dynamic Function eXchange (DFX) enables great flexibility within Xilinx® silicon, empowering you to load applications on demand, deliver updates to deployed systems, and reduce power consumption. Platform designs allow for collaboration between groups, where one group can focus on infrastructure and another on hardware acceleration. However, DFX has fundamental flow requirements that lead to l... » read more

Making Quality A Top Priority in Next-Generation Designs


By Cheryl Ajluni With system design such a complicated task these days, it is increasingly likely that designers will inadvertently overlook some details of the design process, or worse yet, simply not have the time to address them adequately. Time is readily spent focusing on things like performance, area, timing, and power, but what about something a bit more esoteric in nature—namely, qu... » read more
