Hi,
Greetings and welcome to Intel's forum.
May I know the Quartus version(17.0 or 19.1 etc) you are using? And May I confirm with you the DE1 soc you are using is a Cyclone V with ARM SoC core?
When using the Quartus Prime Web Edition, compiling a design with a Nios II/s or Nios II/f processor will produce a time-limited SOF file. As a result, the board must remain connected to the host computer, and the design cannot be set as the default configuration. Designs using only Nios II/e processors and designs compiled using the Quartus Prime Subscription Edition do not have this restriction.
You may need to request a paid license to use the Quartus Prime STANDARD version and using the Nios II/e core to avoid the time_limited part.
I have here a manual on more information of the DE1-soc Computer for your reference: https://ftp.intel.com/Public/Pub/fpgaup/pub/Intel_Material/18.1/Computer_Systems/DE1-SoC/DE1-SoC_Computer_NiosII.pdf
Hope to hear on your feedback and looking forward to your feedback.
Thank you.
Regards,
Kelly
