URANOS - Analysis Methods for the Design of Application-Robust, Nanoelectronic Systems

In the future, integrated circuits will become tinier and more powerful. On the one hand this results in new application areas for the chip industry but on the other hand the development of new chips will become more and more complex. In highly flexible domains like the chip design situations occur where ongoing workflows need to be changed. For instance, when a certain algorithm does not work for a new, smaller chip technology the ongoing chip design process has to be adapted. Such a situation can not be handled by traditional workflow systems. The URANOS research team of the University of Trier explores and improves the chip design process by developing novel methods and tools of agile workflow technology for long-term workflows.

Consortium

The consortium consists of eight partners:

Funding

The URANOS project is funded by the German Ministry of Education and Research (BMBF) under grant number 01M3075 from Juli 2005 to June 2008.

Agile Workflow Technology

Agile workflow technology is a recent research area that deals with the structural adaptation of ongoing workflows. The interleaving of build-time and run-time provides novel requirements for both the workflow modelling language and the workflow enactment service. The URANOS research team at the University of Trier focuses on novel methods and tools for agile workflow technology including:

  • Support of huge, agile process models with thousands of tasks.
  • Facilitating that some parts of a workflow continue with the execution of tasks while other parts are being modified.
  • Late-modelling and hierarchical decomposition of workflows.
  • Change reuse: how former experience from the adaptation of workflows can be applied for the adaptation of an ongoing workflow.
  • User friendly tools for the modelling, adaption, and monitoring of agile workflows.

Tools and Demos

We developed a novel, agile workflow system for long-term processes that is part of the overall Framework CAKE (Collaborative Agile Knowledge Engine).

We invite you to watch a demonstrator movie that shows several of our tools and their importance for the chip design. movie
