## 1.8.7. Create a Compressed Configuration File

You can create a compressed configuration file in two ways. The first way is to run quartus_cpf with an option file that turns on compression.

To create an option file that turns on compression, type the following command at a command prompt:

quartus_cpf -w <filename>.opt

This interactive command guides you through some questions, then creates an option file based on your answers. Use --option to cause quartus_cpf to use the option file. For example, the following command creates a compressed .pof that targets an EPCS64 device:

quartus_cpf --convert --option=<filename>.opt --device=EPCS64 <file>.sof <file>.pof

Alternatively, you can use the Convert Programming Files utility in the Intel® Quartus® Prime software GUI to create a Conversion Setup File (.cof). Configure any options you want, including compression, then save the conversion setup. Use the following command to run the conversion setup you specified.

quartus_cpf --convert <file>.cof
