Pi placement

Bonjour,
j′aurai voulu savoir quelle distinction faite vous entre les différentes possibilités proposées pour le Pi placement :
  • Fonction numérique non interface
  • Fonction numérique d′interface
  • Fonction analogique bas niveau non interface
  • Fonction analogique bas niveau interface
  • Fonction analogique puissance non interface
  • Fonction analogique puissance interface
Dans le Guide Fides, il ne donne aucune précision dessus.
Merci d′avance de votre réponse
Cordialement

FIDES Tutorial ?

Hi ,

I am just wondering if there are any tutorials on how to use the FIDES software about. Or if anyone has written up a sort of "dummies guide". I feel FIDES has all the attributes to be a great tool but I am having problems in getting started. Therefore I am wondering if there are perhaps a tutorial taking you through an example prediction.

Basically I have a parts list of a control card I want to evaluate, is is therefore just a case of populating the component workbook with the parts list?

Any help would be much appreciated.

Différence/ressemblance entre durée de vie et MTBF des composants passifs

Bonjour à tous,

j′ai une question qui m′intrigue beaucoup portant sur la durée de vie (DdV) des composants électroniques, "non-réparables", telles que les diodes.

D′après des calculs effectués sur certains standards de prévision de fiabilité permettant de calculer la DdV des composants élec (exemple du RdF2000), on trouve que ces deux entités sont égales! alors qu′en réalité, elles ne représentent pas la même chose.

Schedule for the next release of FIDES Guide

Dear All,

The release of the new FIDES Guide has been a bit delayed... It is only because every partners involved want this document to be the best possible.

It it still programmed for the end of 2008. But it may comes only at the begining of 2009...

We appologize for the delay to all users that are already waiting for this document.

Wear Out Phase Prediction

It would be nice to start a discussion about the wear out phase of the electronic lifecycle.

The wear-out phase is often modeled with the normal distribution (RIAC) but I haven′t seen any good examples of mean or standard deviations used in such models.

Anecdotal evidence seems to point to new electronics lasting three to ten years, CRT TVs lasting decades and radios lasting as long as forty years.
