[comp.lsi.cad] standard graphics/CAD file formats?

clements@cs.utexas.edu (Paul C. Clements) (12/12/90)

An ongoing research project at the University of Texas is building a
software engineering tool to let people specify programs in a graphical
language.  The graphs are visually similar to hierarchical flowcharts,
dataflow diagrams, VLSI designs, etc.

Question:  Is there a standard file format that we should be using
to represent the positions of the graph components on the screen?
One that will allow us to interface with other graph-processing 
software that we might find useful?   One that we will find computationally
convenient?  Other reasons?

Replies by e-mail appreciated.   I'll mail a summary of responses to
anyone who's interested (or post if volume warrants it).
