Max 10 Configuration Pins

I am planning to program my Max 10 via JTAG interface and USB Blaster. Is it necessary to define the pins nSTATUS, CONF_DONE, and nCONFIG in my top level module? Also how do assign them in the pin pl...

Those pins are dedicated FPGA pins. Therefore, you cannot touch them in pin planner.

There is the MAX10 Documentation (simple google search): https://www.altera.com/en_us/pdfs/literature/hb/max-10/ug_m10_config.pdf

Figure 3-1 shows how to connect USB blaster to JTAG pins. nSTATUS, CONF_DONE, nCONFIG are set internally to display the status of configuration.

CONF_DONE is a bidirectional pin usually. So you can hold it low to prevent the FPGA from running once configured.
