I need to change whether or not there are weak pull_ups on an FPGA's I/O pin but don't have the privilege of re-compiling the whole design. A new gateware file would need to be created, but since...

Hi KOber,

Apparently, pull up the I/O without re-synthesizing the design is not possible.

You can only pull up it using Pin Planner or Pin assignment. Then you have to compile it to create a new bit stream.

Thanks

ShafiqY_Intel,

Can you put in an Arria 10 feature request for the ability to add pull ups to I/O without re-synthesizing the design, and provide me with the change request number?

Thank you
