Honored Contributori'm using quartus ii 9.1 with incremental compilation and i have thie error message "can't place multiple pins assigned to pin location w9 " but in pin editor allows to place that pin and one only pin is assigned to that location. what's happening is there a known bug?.
Thanks
Honored ContributorHi,
can you tell which device you are using? I think you´re problem has to do something with the configuratiuon pins of your specific device.Honored ContributorDid you expand the error message? It should have more details about conflicting assignments.
Honored ContributorHi,
no conflict with dedicated pins, the conflict is with another pin whose assignment is made from the fitter and not form me. I am using an EP2C35. Why the fitter assign some pin location?Honored ContributorHi,
if the case is F484 you should get no problems. You are right. What kind is the second assignement. Can you give some detailed information?Honored ContributorThe only automatic assigned function for pin W9 of EP2C35F484 is differential pair with Y9. But as said, the full error message text should tell.
Honored ContributorTx_Ena_Block_New:inst|clk_tx[5] Location PIN W9 QSF Assignment Tx_Ena_Block_New:inst|clk_tx[5] Location PIN G5 Post-Fit Property
After a compilation with all design blocks with postfit preservation level I find this "fitter incremental compilation conflict" I have assignd the output to pin W9 but it seems it is assignd automatically to G5. I don't understand why. In the resource section repot I find many output pins i have assigned as virtual assigned to a phicical output by the fitter? Why?
