If the full design configuration file is not required, then a single
partial bitstream can be created on its own. With a full design configuration checkpoint
loaded in memory, use the -cell
option to identify the
instance for which a partial bitstream is needed. The name of this partial bitstream can
be given, as it is not automatically derived from the Pblock name.
write_bitstream -cell rp1 RM_count_down_partial.bit
This creates only a partial bitstream for the RP identified.
CAUTION:
Do not run
write_bitstream
directly on RM checkpoints; only
use full design checkpoints. RM checkpoints, while they are placed and routed
submodules, have no information regarding the top level design implementation, and
therefore would create unsuitable partial bit files.
