CHAPTER 5: PLACE & ROUTE
ANALYZING FITTING RESULTS
98 ■ INTRODUCTION TO QUARTUS II ALTERA CORPORATION
To edit assignments in the Timing Closure floorplan, you can click a
resource assignment and drag it to a new location. While dragging a
resource in the Timing Closure floorplan, you can use rubberbanding to
display a visual representation of the number of routing resources affected
by the move.
You can view the routing congestion in a design, view routing delay
information for paths, and view connection counts to specific nodes. The
Timing Closure floorplan also allows you to view the node fan-out and node
fan-in for specific structures, or view the paths between specific nodes. If
necessary, you can change or delete resource assignments. For more
information on using the Timing Closure floorplan, refer to “Using the
Timing Closure Floorplan” on page 162 in Chapter 9, “Timing Closure.”
If you want to view more fitting details and make additional fitting
adjustments, the Chip Editor reveals additional details about design
placement and routing that are not visible in the Timing Closure floorplan,
and allows you to make changes by using the Resource Property Editor and
Chip Editor. For more information, refer to “Chapter 13: Engineering
Change Management” on page 213.
Using the Design Assistant to Check
Design Reliability
The Quartus II Design Assistant allows you to check the reliability of your
design, based on a set of design rules, to determine whether there are any
issues that may affect fitting or design optimization. The Design Assistant
