Problem Title:
How to analyze the resources a module or partially completed design consumes?
Problem Description:
Urgency: Standard
General Description:
If you have a partially completed design, how can you determine
what percentage of the device is used and what resources are used?
Solution 1:
Create an EDIF, XNF, or SXNF netlist of the module or design section
you are interested in evaluating.
Command Line:
1. Process your design to the mapped stage using the command below.
The mapper determines the kinds and amounts of physical
resources used. The Place and Route stage simply determines
the arrangement of the resources and the routing used. So you
do not need to wait for the Place and Route stage to complete.
ngdbuild -p <part name> <design netlist>
map <design>.ngd -u
2. The -u option tells the optimizer not to trim unconnected signals
and symbols. This prevents your incomplete design from being
deleted.
3. Open the <design>.mrp file using a text editor. Go to the
bottom of the Map Report, there you will see a Design Summary.
The Design Summary lists the resources used by the part of the
design that you processed.
Graphical Interface:
1. Using the Design Manager, create a project for your netlist.
Select File->New Project from the Design Manager menu.
2. Create a version and revision. Select Design->New Version
and Design->New Revision fro the Design Manger menue.
3. Select the revision and click on the Flow Engine toolbar button.
4. In the Flow Engine select the Setup->Options menu item.
5. Click on the Edit Template button for the Implementation
Template. On the Optimize & Map tab, make sure that the
Trim Unconnected Signals button is unselected. This prevents
the optimizer from deleting your whole design.
6. In the Flow Engine select the Setup->Stop After... menu item.
Select to stop after Map. The mapper determines the kinds and
amounts of physical resources used. The Place and Route stage
simply determines the arrangement of the resources and the
routing used. So you do not need to wait for the Place and Route
stage to complete.
7. To process your design, from the Flow Engine menu select
Flow->Run.
8. When the Flow Engine completes the Map stage, open the Report
Browser and double click on the Map report. To open the
Report Browser, from the Flow Engine menu select
Utilities->Report Browser.
9. Go to the bottom of the Map Report, there you will see a Design
Summary. The Design Summary lists the resources used by the
part of the design that you processed.
Below is a sample Design Summary:
Section: Design Summary
------------------------
Number of warnings: 5
Number of errors: 0
Number of CLBs: 1185 out of 1296
Flops/latches: 2031
4 input LUTs: 1833
3 input LUTs: 1100
Number of bonded IOBs: 243 out of 256
Number of BUFGLSs: 4 out of 8
