Once all desired Configurations have been placed and routed, bitstreams may be generated. Just as
with Implementation, the Generate Bitstream button in the Flow
Navigator may be used. This launches write_bitstream for all child runs
as well as the active parent. A local right-click call to
write_bitstream on any Configuration is also available.
The pr_verify utility is automatically called prior to write_bitstream on each child Configuration run. This routed database is compared to the parent database to ensure all DFX rules have been met. The results of this check are stored in the run directory under the name <impl_name>_pr_verify.log.
By default, a full design bitstream and all partial (and for AMD UltraScale™
,
clearing) bitstreams are generated for all routed configurations. You can request
specific bitstreams only by utilizing the write_bitstreams options
available. Under the Write Bitstream options category in the Options pane for the
Implementation Run Properties, use the More Options field to
select one of these options:
-
-no_partial_bitfilegenerates only the full configuration file and no partial bitstreams. -
-cell <cell>generates only the partial bitstream for the requested cell.
