CHAPTER 4: SYNTHESIS
ANALYZING SYNTHESIS RESULTS WITH THE RTL VIEWER
80 ■ INTRODUCTION TO QUARTUS II ALTERA CORPORATION
You can also improve design optimization by following good synchronous
design practices and by following Quartus II coding style guidelines.
Analyzing Synthesis Results with
the RTL Viewer
The Quartus II RTL Viewer provides a schematic view of your design. To
run the RTL Viewer for a Quartus II project, you must first analyze the
design by choosing Start > Start Analysis & Elaboration (Processing menu).
You may also perform Analysis & Synthesis or perform a full compilation,
because those processes include the Analysis & Elaboration stage of the
compilation flow. After performing a successful Analysis & Elaboration,
!
Using the quartus_drc executable
You can also run the Design Assistant separately at the command prompt or in a
script by using the quartus_drc executable. You must run the Quartus II Fitter
executable quartus_fit before running the Design Assistant.
The quartus_drc executable creates a separate text-based report file that can be
viewed with any text editor.
If you want to get help on the quartus_drc executable, type one of the following
commands at the command prompt:
quartus_drc -h
r
quartus_drc -help r
quartus_drc --help=<topic name> r
