Configuration Method in Device and Pin Options VS Convert Programming file windoe

Hey,

I would like to know if there is a difference between the "configuration scheme" in configuration tab via "Device and Pin Options" in Quartus Prime, against the "Mode" property via "Convert Programming File" ?

For example, if I choose the Configuration Scheme to be as Active serial x4 in configuration tab ( via "Device and Pin Options"), compiling the project.

After that in the "Convert Programming File" I choose "Mode: Active Serial x1", and create for example a .jic file, there will be any collision? In that case, in which active serial mode the FPGA device will be loaded?

Thank you

    Hi there,

    Strell is right. The setting in ‘Configuration method’ will be saved in .qsf file and .sof file after the assembler. The configure method should follow these settings.

    If you wanna change the configure method, an easy way is using the ‘CPF tool’. Just like Strell said, the CPF tool is for converting an existing programming file into a different format for a different use.

    Best regards,

    As the name implies, the CPF tool is for converting an existing programming file into a different format for a different use. So if you set the config scheme initially to ASx4, the file generated from a full compilation must be used for an ASx4 config scheme. If you then take that file and convert it to ASx1, then you can use the new file if you are set up for ASx1. The original file can still be used for ASx4.

    If you recompile the design, it will still use the setting specified in device and pin options, ASx4 in your example.
