Pin Assignment failed to be downloaded to the FPGA board

[Altera_Forum]

Hi, All, 

 I am using the Cyclone II DE board and had a strange problem.  Once I changed the pin assignment, e.g., I changed the reset signal from push button KEY0 to KEY1; then I re-compiled the project and downloaded it again on to the board. Surprisingly, when I monitored the signals using SignalTap, it seemed that the "reset" signal was still controlled by the previous setting, namely KEY0, how come??  I tried to download again and again but seems the pin assignment never got changed to tally with my new assignments. I am now really confused, really hope some one could help~ =)  Thanks a lot!  Regards grit

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  GPK

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.

When you use post-fitting nodes in Signaltap the Partition Top ( that is a defalut partition in every project) preserve Level is set to "Placement & Routing" and a new pin assignment will be ignored. Look into your messages, I sure sure you will find an info about this issue.  Kind regards  GPK
