Description

In the 2012.2 Vivado tool, if you open iMPACT twice from a given Vivado project, iMPACT will crash the second time.

Solution

There are two solutions to this problem:

• Delete the <design name>.data\impact\impactdefaultproj.ipf file. This must be done each time.
• Run iMPACT from command line or from the Start menu.

This issue has been fixed in Vivado 2012.3 tools.
