ID:35016 Found partition port(s) not driving logic, possibly wasting area
CAUSE: The partition ports specified in the sub-messages have no fan-out. The implications are as follows:
- If a specified partition port is an input port, no logic within the partition currently depends on it.
- If a specified partition port is an output port, no logic outside the partition currently depends on it.
ACTION: If you intend to connect the specified partition ports in a subsequent incremental compilation, no action is required. If you want to reclaim the wasted area, you may restructure the partitions such that the specified unused port is not at a partition boundary. You may also provide a wrapper module around an entity instance to hide its unused ports, and set the wrapper as a partition instead of the containing entity instance. You may use the Incremental Compilation Advisor to detect the presence of dangling partition ports, as well as other potential issues in the current design.
