SYNPLIFY: How is the top level module or entity/architecture determined?

Description

Keywords: Synplify, VHDL, Verilog

Urgencey: Standard

General Description:
How does Synplify determine the top level module or entity/architecture?

Solution

For synthesis, Synplify scans the input source files from top to bottom of
the source file list. For Verilog, the top level module is the last module it
finds that is not instantiated somewhere in the design. For VHDL, it is the
last architecture of the last entity that it finds. Therefore it is best for both
languages to put your to level as the last object in the last design file in
your list of input source files.
