Pin Assignment failed to be downloaded to the FPGA board

--- Quote Start ---

first have look into the <>.pin file. It is locaterd in the Quartus RunDir. Search for your signal and check whether the assignment changed or not.

If not, how do you change the assignment ? Using the Assignment Editor ? Which Version of Quartus do you use ?

Kind regards

Hello, GPK,

Thanks for replying!

Now the problem seems have gone. The solution is that I re-added nodes inside the SignalTap each time I changed the pin assignment in Pin Planner, and then re-compile.

I am using Quartus II 9.0 SP2.

Thanks once again.
