So I propose a name of "SDx Group" (note creative use of caps and lower case). The "SD" portion standing for "Software Defined"
How about UDx for User Defined (unknown) or UCx (User Configurable). The FPGA, which seems to be the center of whatever this is, is not software defined unless you add a soft processor core to it and then program and run that core. But, the user loads a configuration file into the device that defines the hardware function it is performing.
