Error:I/O std LVDS on output I/O pin cannot have Termination logic option setting

Hi,  

 

I have created simple schematic design [consists of 4-bit counter and Ibufout-diff [from IP catlog]. While compilation, it`s showing error.  

 

one more issue is, i have assigned only 4 pins[3..0], but in pin planner its taking extra pin count. I dont know why.  

 

Please look over my design and Pin planner diagram.

Your pictures are way too small to see anything.

I am unable to upload the project. So please check my attachment. In Schematic design, total output pins are 4. But in Pin planner output ports are missing only clk and reset pin is available

I am new to Altera Quartus. Doing LVDS testing from Altera Cyclone to Xilinx Board. Can anyone conform whether my block design is right or wrong. Design Flow sending input from 4-bit counter to single-ended input and differential output Alter buffer. Then passing differential output LVDS signal from Cyclone V board to Xilinx Custom Board. I tried lot but it is not working. So, anyone please guide me.

It looks fine now. Be sure to select the LVDS I/O type for your output pins in the pin planner.
