The top-level System Generator token has
to be configured to indicate that the Code Generation must proceed for a multiple clock
design. This is indicated by turning on the Enable multiple
clocks check box in the top-level System Generator token. This indicates to the Code Generation engine that
the clock information for the Subsystems src_domain and
dest_domain must be obtained from the System Generator tokens contained in those Subsystems. If
this check box is not enabled, then the design will be treated as a single clock design
where all the clock information is inherited from the top-level System Generator block.
