Against my better judgment, I tried using 8.2sp3 again tonight by converting and building an older, working 6.3 project.
I created a new build directory, copied in the old .npl and .ucf files, pointed 8.2sp3 at the old .npl project file, said yes to the .npl format translation messages, then did a bitstream build.
When I went back to my external text editor, I was greeted by many warnings that my open source files { stored outside the project directory, not 'local copies' } had been updated outside the editor.
Checking further, the file contents matched my backups, but all of the source file timestamps had suspiciously been changed to the exact same time/date as the creation of the .zip file used by ISE for the old project backup, as though ISE had decided to "touch" all the source files ( see directory listings below ).
Has anyone else seen this behavior ?
Does this only happen during the import of an old .npl file, or does the ISE8.2 project manager decide to clobber the file timestamps of all user sources on other special occasions ?
