ISE 10.1 does not reload the user constraints file

[Ale (Gast)]

Hei,

I have to use ISE 10.1 because I have a spartan2 design (must be 5V 
tolerant).
If I create a new project and add a user constraints file with some 
pins, and then I delete some pins (not yet used) the mapper complains 
that the pins I deleted from the ucf are unconnected. As if the pins 
were still there.

Choosing clean all project files and re-run all does not solve the 
problem...

Any ideas ?

ps: I am planning on using the command line tools if I can avoid this 
problem.

Any tips are welcome.

Two solutions:

1. remove the pins in .ucf too
2. add all pins to .ucf and your top-level design file and give them 
some default values.

It may not have been clear from my previous post... but the pins are not 
there at all, not in the hdl source, and not in the ucf file. The mapper 
complains as if they were still there (they are not).

Ok. Did you try "Cleanup Project Files"?

Yes, I did...

I also deleted all directories... nothing helps :/.
I read somewhere that the .ise file would not be updated...
