The Quartus II Design Assistant analyzes the reliability of a design based on
Altera-recommended design guidelines or design rules during design compilation.
The Design Assistant checks rules related to areas such as clocks, resets, timing
closure, and non-synchronous design structure. You can select the areas you want the
Design Assistant to check and the Design Assistant will report any design violation
based on the settings you specified. The HardCopy rules are not applicable to designs
targeting Cyclone III devices.
To turn on the Design Assistant, on the Assignments menu, click Settings. Select the

Quartus II Handbook.
The Quartus II incremental compilation feature preserves the results and performance
of the unchanged logic in your design as you make changes elsewhere, allowing you
to perform more design iterations, achieve timing closure efficiently and reduce
compilation time when changes are made to certain partitions of the design.
In an incremental compilation flow, a large design is split into smaller partitions that
can be designed separately and independently to simplify the design process and
reduce compilation time. Good partition and floorplan design helps lower-level
design blocks meet top-level design requirements, reducing the time spent integrating
and verifying the timing of the top-level design.
