Cyclone IV GX Transceiver Starter Board, Clocks & Ports issue with HDL Coder (MATLAB)

You can find pin information called pin-out on altera.com.

Go https://www.altera.com/products/fpga/cyclone-series/cyclone-iv/support.html

Click 'Device Pin-Outs'

Click 'Cyclone IV'

Search 'EP4CGX15' and click Pin-Outs (XLS)

Your device 'F14' package has 169 pins, so refer to column F 'F169'. I hate this translation :(

Accoding to the spreadsheet, M7 pin is located in Bank B4, the function of the pin is CLK14 or DIFFCLK_6p. This is the best choice for clocks. I always uses differential I/O standard for clocks to avoid unexpected behavior caused by glitch on the clock, so I use DIFFCLK_*p pins.

D10 is a general I/O pin, it should be good.

R1 and R4 cannot be found in the spreadsheet. They must be changed to proper pin locations.

I hope this helps you.
