Everything you always wanted to know about worst-case (but were afraid to ask) …
Technische Universitaet Muenchen –
Process corners, corner cases, worst case parameter sets, …; there are a lot of myths about certain parameter sets that are supposed to capture some kind of measure for variability of a circuit manufactured in a semiconductor technology. But what are these corners really? How are they determined? How should the results of a worst-case simulation be interpreted? And how can I get an estimation of the yield, more specifically, the parametric yield? These are questions that every designer of analog and mixed-signal circuits is confronted with in his every-day life of designing complex circuits in ever-advancing technologies with ever-increasing transistor variability. The first part of the talk will give some answers.
Constraints are key elements of analog design automation: a mathematical optimization tool would not be applicable if it would not be provided with constraints to keep transistors in saturation, to take care of symmetrical sizing, for instance. Interestingly, the netlist of an analog circuit inherently can provide a lot of constraints. The second part of the talk presents a method to automatically extract constraints out of a given netlist. It consists of two parts. First, an analysis of the hierarchical structure of a circuit is described. Second, a signal path analysis is presented. The overall outcome are constraints for sizing and placement, as well as a construction plan for analog placement. It will be illustrated how to use this outcome in sizing and placement of analog circuits.
Bio: Helmut Graeb got his Dipl.-Ing., Dr.-Ing., and habilitation degrees from Technische Universitaet Muenchen in 1986, 1993 and 2008, respectively. He was with Siemens Corporation, Munich, from 1986 to 1987, where he was involved in the design of DRAMs. Since 1987, he has been with the Institute of Electronic Design Automation, TUM, where he has been the head of a research group since 1993. His research interests are in design automation for analog and mixed-signal circuits, with particular emphasis on Pareto optimization of analog circuits considering parameter tolerances, analog design for yield and reliability, hierarchical sizing of analog circuits, analog/mixed signal test design, discrete sizing of analog circuits, structural analysis of analog and digital circuits, and analog layout synthesis. Dr. Graeb has, for instance, served as a Member of the Executive Committee of the ICCAD conference, as a Member or Chair of the Analog Program Subcommittees of the ICCAD, DAC, and D.A.T.E conferences, as Associate Editor of the IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS PART II: ANALOG AND DIGITAL SIGNAL PROCESSING and IEEE TRANSACTIONS ON COMPUTER-AIDED DESIGN OF INTEGRATED CIRCUITS AND SYSTEMS, and as a Member of the Technical Advisory Board of MunEDA GmbH Munich, which he co-founded. He is a Senior Member of IEEE (CAS) and member of VDE (ITG). He was the recipient of the 2008 prize of the Information Technology Society (ITG) of the Association for Electrical, Electronic and Information Technologies (VDE), of the 2004 Best Teaching Award of the TUM EE Faculty Students Association, of the 3rd prize of the 1996 Munich Business Plan Contest.

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.
