A Practical Approach to Modeling ESD Protection Devices for Circuit Simulation

A Practical Approach to Modeling ESD Protection Devices for Circuit Simulation

Lurking inside of every Mosfet is a parasitic bipolar junction transistor (BJT). Of course, in normal circuit operation the BJT does not play a role in the device operation. Accordingly, SPICE models for Mosfets do not behave well when the BJT is triggered. However, these models work just fine for most purposes. The one important… Read More

Electrical Reliability Verification – Now At FullChip

Electrical Reliability Verification – Now At FullChip
by Alex Tan on 04-25-2018 at 12:00 pm

Advanced process technology offers both device and interconnect scaling for increased design density and higher performance while invoking also significant implementation complexities. Aside from the performance, power and area (PPA) aspects, designer is getting entrenched with the need of tackling more reliability … Read More


Stress and Aging

Stress and Aging
by Bernard Murphy on 04-05-2018 at 12:00 pm

These failings aren’t just a cross we humans bear; they’re also a concern for chips, particularly in electrical over-stress (EOS) and aging of the circuitry. Such concerns are not new, but they are taking on new urgency given the high reliability and long lifetime expectations we have for safety-critical components in cars and… Read More


Robust Reliability Verification – A Critical Addition To Baseline Checks

Robust Reliability Verification – A Critical Addition To Baseline Checks
by Alex Tan on 03-01-2018 at 12:00 pm

Design process retargeting is acommon recurrence based on scaling orBOM(Bill-Of-Material) cost improvement needs. This occursnot only with the availability of foundry process refresh to a more advanced node,but also to any new derivative process node tailored towards matching design complexity, power profile or reliabilityRead More


Snapback behavior determines ESD protection effectiveness

Snapback behavior determines ESD protection effectiveness
by Tom Simon on 12-14-2017 at 12:00 pm

Terms like avalanche breakdown and impact ionization sound like they come from the world of science fiction. They do indeed come from a high stakes world, but one that plays out over and over again here and now, on a microscopic scale in semiconductor devices – namely as part of electrostatic discharge (ESD) protection. Semiconductor… Read More

Webinar: Signoff for Thermal, Reliability and More in Advanced FinFET designs

Webinar: Signoff for Thermal, Reliability and More in Advanced FinFET designs
by Bernard Murphy on 09-17-2017 at 7:00 am

In automotive applications, advanced FinFET processes are great for high levels of integration and low power. But they also present some new challenges in reliability signoff. Ansys will be hosting a webinar to highlight the challenges faced by engineers trying to ensure thermal, electromigration (EM) and electrostatic discharge… Read More


Simulating ADAS

Simulating ADAS
by Bernard Murphy on 05-04-2017 at 7:00 am

Simulation is a broad technique spanning certainly digital logic and circuit simulation but also methods beyond these which are particularly relevant to ADAS design. In fact, much of the design of full ADAS systems begins and ends with these types of modeling. This is in part due to the need fully validate integrity and reliability… Read More
