184.108.40.206. SOF Manager
The SOF Manager is in the JTAG Chain Configuration pane.
With the SOF Manager you can embed multiple SOFs into one .stp file. This action lets you move the .stp file to a different location, either on the same computer or across a network, without including the associated .sof separately. To embed a new SOF in the .stp file, click the Attach SOF File icon .
As you switch between configurations in the Data Log, you can extract the SOF that is compatible with that configuration.
To download the new SOF to the FPGA, click the Program Device icon in the SOF Manager, after ensuring that the configuration of your .stp matches the design programmed into the target device.
