Development of Radiation Hard 150nm Standard Cell Library
João Baptista Martins,
Federal University of Santa Maria –
The effects produced by radiation on integrated circuits can be classified into Single Event Effects (SEE) related to transient problems and Total Ionization Dose (TID) effects that arise due to the long exposure time ionizing radiation. The mitigation of these effects on integrated circuits can be done in three ways: Manufacturing Process Level, Architectural Level (redundancy) and Layout Level. The work presented here deals with the third way of mitigation, that is, the cell library design of radiation tolerant integrated circuits. Designed and manufactured in silicon on 150nm technology, the SMDH-RH library is based on the use of guard rings and the application of closed geometry techniques (ELT – Enclosed Layout Transistor). The library includes simple and complex digital logic gates. It was tested in space as payload of a Nanosatellite (NanosatC-Br1), launched in space in 2014 and in activity still, being approved its operation and functionality.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
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.
