12 years agoProbably the existing '.bsf' is read-only so you can't write it.
Firstly control that the '.bdf' is open and selected in the quartus IDE. Then check that no program is using that file and be sure to have the right permissions on the folder where your project is placed and on the '.bsf' itself. If that not helps try deleting the existing '.bsf' and then recreate it. Hope this helps. Have a nice day.
