If Project Navigator determines that there has been a modification to the source code, UCF, or synthesis/implementations options, of a project, attempting to open a process report by double-clicking causes the entire flow to be rerun starting at the first process where a change was detected.
If the synthesis options have been changed, double-clicking the "map report" process causes Project Navigator to launch a new synthesis, NGDBuild, and MAP process before the MAP report is opened.
How can I view a report with ISE without reimplementing the design?
In the Processes window of Project Navigator:
1. Right-click the icon representing the report that you would like to view (for example, "View Synthesis Report" or "Map report").
2. Then select "Open without updating."
