Error (169079): Pad 138 of non-differential I/O pin 'pin93' in pin location F13 is too close to pad 136 of differential I/O pin 'APBLCLK(n)' in pin location G16 -- pads must be separated by a minimum of 5 pads. Use the Pad View of Pin Planner to debug.

Hi yzhan275,

 

Can you provide me the background of your design for further debug?

e.g. (device full name, quartus version and etc)

 

Thanks

Hi yzhan275,

 

For this issue, the placement of your pin is too close. The pad must be separated by min 5 pads.

 

solution: Use the Pad View window of the Pin Planner to check the pad placement, and then assign one of the conflicting I/O pins to a different location

 

Thanks
