Modeling and Simulation of Time Domain Faults in Digital Systems
João Paulo Cacho Teixeira,
The purpose of this seminar is to present and discuss novel modeling and fault simulation techniques for two types of dynamic faults in digital systems: transient power supply voltage drops and transient delays in logic elements or signals paths. Techniques and tools currently used for permanent faults are reused for dynamic (permanent) and intermittent faults. For transient power supply voltage drops, two approaches are proposed: delay fault injection in all logic elements of the CUT (Circuit Under Test), or modulation of the clock and observation rate. For transient delays (e.g., SEU), single delay injection is performed at logic element level. Delay modulation is carried out by fault injection using the PLI interface of the commercial Verilog simulation tool, from Cadence. Preliminary results, using an ISCAS’85 benchmark circuit, show that CUTs with long critical paths are very sensitive to power supply transients. Moreover, a pseudo-random test pattern can be used to identify the dependence of the CUT sensitivity to delay faults on defect size, for a given clock period.

Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
