webpack crashed whilst synthesising my design. This is the first time
that I have had this. I have managed to get the design to synthesise
properly and do a p&r netlist. I didn't change the design.

The things that are missing are mainly cosmetic but I would like to
reinstate them. The snapshot list is blank. I can see a snapshot
directory and there are files inside it. How do I get webpack to
re-create the snapshot area? When I do a synthesis run I don't get an
errors/warnings report. Yes I can look at the synthesis log. It would be
good to get the list of errors and warnings on the design summary page.

Any ideas/pointers. Thanks in advance Andy

Whenever ISE/Webpack does something strange, clicking on the Project
Tab, and then Cleanup Project Files often helps. I don't know if this
will solve your problem or not.

I tried that first thing. It didn't report any files to tidy up.

I've set the correct fpga family, added the root module and updated a
few of the synthesis settings.

If I do a project clean up will I lose these changes? Andy

Try to build a new project and copy - ONLY - your source files.
( ISE have some "artificial intelligence" issues )

By experience; do your self your personal backups/snapshots using a
script or copy your working folders to a backup location.
If you use Windows, a WinZIP command line batch file is a good and
simple option, you have options on Linux also.

If you're running ISE version 10.1 you should have a restore
script for the project <project_name>.restore

Instructions for regenerating the project from the restore
script are inside the script. Basically:
In the GUI click the TCL Shell tab
change the directory to your project directory
type "source <project_name>.restore"
type "restore"

If you're lucky and the original restore file hasn't
already been clobbered, you should get back all of
your settings.

Regards,
Gabor

Trouble is, running ISE to discover the broken project file, you are liable to
rewrite the .restore file...

Apologies for the delay. My home project got sidelined by some holiday.
Synthesis in all forms is working OK. I'll run it until my testbench
agrees with what I want and then move to a new project name/directory.
On my FC8 desktop I've not had this sort of fault. On my FC11 laptop I
get spontaneous crashes without any particular reason. dmesg shows a
segfault.

I will keep a close eye on this. Thanks for your time Andy.
