pin assignment problem

--- Quote Start ---

You didn't yet post significant information that shows what your pin assignment problem is.

I experience limitations of the pin planner if pins are already previously assigned. E.g. deletion of assignments isn't fully supported. In this case you can perform all intended actions in the assignment editor.

Hi shipra7993,

Which Quartus version are you using? Please be specific. Your screen shot shows there are automatically fitter location pins. Even without specific pin assignment you should be able to find the input or output or bidirectional pin nodes from the Signal Tap. In the SignalTap, you just need to set fitter option to Pins:all and then click List where the node finder will automatically detect any pins regardless assigned or unassigned pins.

If you still unable to assign the pin location manually in the Pin Assignment GUI, you can still set the pin location in your .qsf file. You can check and edit the .qsf file for your pin assignment by using the following syntax:

set_location_assignment <pin location> -to <input/output/bidirectional pin>

For example:

set_location_assignment PIN_L28 -to LED[0]

As long, the .qsf file contained the pin assignment information (set_location_assignment), the pins are correctly assigned.

Regards,

It's always possible to assign pin locations in assignment editor, as mentioned in post# 2. Apparently you didn't try yet.

It's not clear yet which of your assignments are not accepted and what's the respective error message.
