Design flow management in the NELSIS CAD framework

In this paper a new approach for design flow management is presented. We describe how the inputloutput relations between took can be defined in afIOwmap. For this, several concepts are introduced. such as defrning activities for took, run-time activity identifrcatwn, hierarchical flow graphs, modification versus extension, and the possibility to have loops in the flowmap. We also address tool scheduling and the integration of design flow management in the architecture of a frame-based design system.
