Hi Chandu Sri, 

Do you able to resolve the error (21961)? 
 
This might be related to Arria 10 device.
Error(21961): Input port OE of a "LVDS" I/O output buffer "*|gpio_0|core|i_loop[0].altera_gpio_bit_i|output_buffer.obuf_0" is not supported. | Altera Community - 340667

Could you try regenerating the IP?
If the issue persists, you may also try instantiating a new GPIO IP with the same settings and replacing the existing instance.

Regards,
Richard Tan

      Hi Richard,

      I could get this error working. had to enable pad_out_n signal from GPIO IP core as my I/O standard is LVDS. currently I am getting error for pin assignments.

      working on clearing the I/O assignments. will raise a new ticket if issue is not resolved at my end.

      Thanks for the support,

      Regards,

      Chandu sri
