ANALYZING SYNTHESIS RESULTS WITH THE RTL VIEWER
ALTERA CORPORATION INTRODUCTION TO QUARTUS II ■ 81
you can display the RTL Viewer window by choosing RTL Viewer (Tools
menu). In addition to the schematic view, the RTL Viewer has a hierarchy
list, which lists the instances, primitives, pins, and nets for the entire design
netlist. See Figure 6.
Figure 6. RTL Viewer Window
The RTL viewer displays the Analysis & Elaboration results for Verilog HDL
or VHDL designs, and AHDL Text Design Files (.tdf), Block Design
Files (.bdf), Graphic Design Files (.gdf), or files that are synthesized within
the Quartus II software. For VQM Files or EDIF netlist files that were
generated from other EDA synthesis tools, the RTL Viewer displays the
hierarchy for the atom representations of WYSIWYG primitives.
You can select one or more items in the hierarchy list to highlight in the
schematic view, and vice versa. The RTL Viewer allows you to adjust the
view or focus by zooming in and out to see different levels of detail,
searching through the RTL Viewer for a specific name, moving up or down
in the hierarchy, or going to the source that feeds the selected net. If you
want to adjust the fan-in or fan-out display, you can expand it or collapse it.
You can use the tooltips to see node and source information for individual
items. You can also select a node in the RTL Viewer and locate them in the
