R
PartialMask0, PartialMask1, PartialMask2
Generates a bitstream comprised of only the major addresses of block type <0, 1, or 2> that
have enabled value in the mask. The block type is all non-block ram initialization data
frames in the applicable device and its derivatives. The mask is a hex value.
PartialLeft
Adds the left side frames of the device into the list of frames to write out in a partial
bitstream. This includes CLB, IOB, and BRAM columns. It does not include the center
global clock column.
PartialRight
Adds the right side frames of the device into the list of frames to write out in a partial
bitstream. This includes CLB, IOB, and BRAM columns. It does not include the center
global clock column.
Persist
This option is needed for Readback and Partial Reconfiguration using the SelectMAP
configuration pins. If Persist is set to Yes, the pins used for SelectMAP mode are prohibited
for use as user I/O. Refer to the datasheet for a description of SelectMAP mode and the
associated pins.
