Saving/Loading registers to/from disk
Registers can be saved to disk by first selecting them in the DV main window,
then choosing the Write selected SDF(s) to file under the File
menu. For each register that you have selected, a dialogue window
will pop up, in turn, where you can enter the disk location and file name
where you want to save the register. The register will be saved in SDF
format. Single registers can also be loaded into the DV using the Read
SDF from file option under the File menu (or using sdftodv).
