Automotive Chip Design Workflow


Stewart Williams, senior technical marketing manager at Synopsys, talks about the consolidation of chips in a vehicle and the impact of 7/5nm on automotive SoC design, how to trade off power, performance, area and reliability, and how ISO 26262 impacts those variables. » read more

The Future Of Embedded Monitoring, Part 1


Shall I compare thee to a…Rolls Royce jet engine? ‘There is a new era dawning whereby deeply embedded sensing within all technology will bring about great benefit for the reliability and performance of semiconductor-based products.’ These were my words during a presentation to an industry audience in China back in September 2015. During that same presentation, somewhat to the consterna... » read more

Analog: Avoid Or Embrace?


We live in an analog world, but digital processing has proven quicker, cheaper and easier. Moving digital data around is only possible while the physics of wires can be safely abstracted away enough to provide reliable communications. As soon as a signal passes off-chip, the analog domain reasserts control for modern systems. Each of those transitions requires a data converter. The usage ... » read more

Improving In-System Test With Tessent VersaPoint Test Point Technology


This paper describes a new versatile test point technology called VersaPoint, which has been developed specifically to work with designs implementing mixed EDT/LBIST methodologies to reduce EDT pattern counts and improve Logic BIST (LBIST) test coverage. VersaPoint test points can reduce compressed pattern counts 2X to 4X beyond compression alone and improve LBIST test coverage beyond what is p... » read more

Automakers Changing Tactics On Reliability


Automakers are beginning to rethink how to ensure automotive electronics will remain reliable over their projected lifetimes, focusing their efforts on redundancy, more data-centric architectures and continued testing throughout the life of a vehicle. It is still too early to really know how automotive chips actually will perform over the next 15 to 20 years, especially AI logic developed at... » read more

Scan Diagnosis


Jayant D’Souza, product manager at Mentor, a Siemens Business, explains the difference between scan test and scan diagnosis, what causes values in a scan test to change, how this can be used to hone in on the actual cause of a failure in a design, and how to utilize test hardware more efficiently. » read more

Hierarchical DFT On A Flat Layout Design


The use of hierarchical DFT methods is growing as design size and complexity stresses memory requirements and design schedules.  Hierarchical DFT divides the design into smaller pieces, creates test structures and patterns at the core level, then retargets the core patterns to the chip level. But, if you need to perform the physical place and route on the full flat design, can you still take a... » read more

ON Semiconductor Reduces Memory BiST Insertion Time By 6X With Tessent Hierarchical Flow


This paper describes a case study on the insertion of memory BiST for an ON Semiconductor multi-million gate-level netlist with 300 memory instances. The physical implementation will be done using a flat layout. Two different methodologies can be applied when it comes to physical implementation; hierarchical or fullflat. When performing physical implementation as full-flat flow, typically the D... » read more

BiST Grows Up In Automotive


Test concepts and methods that have been used for many years in traditional semiconductor and SoC design are now being leveraged for automotive chips, but they need to be adapted and upgraded to enable monitoring of advanced automotive systems during operation of a vehicle. Automotive and safety critical designs have very high quality, reliability, and safety requirements, which pairs pe... » read more

In-Chip Monitoring Becoming Essential Below 10nm


Rising systemic complexity and more potential interactions in heterogeneous designs is making it much more difficult to ensure a chip, or even a block within a chip, will functioning properly without actually monitoring that behavior in real-time. Continuous and sporadic monitoring have been creeping into designs for the past couple of decades. But it hasn’t always been clear how effective... » read more
