synthesis tool recognizes all the lower level blocks used in the top-level code and
synthesizes them together to create a single bitstream.

submodules to check syntax. To check the schematic file, run Check Design Rules, found under
the Design Utilities process.
After you have checked all the modules, highlight the top level module, then go down to
the process tree and right-click on Synthesize (under Implement Design) and select
Properties.
In the Sources window, ensure that “top.vhd” (or “top_sch” for schematic flows) is
highlighted.
In the Process window, expand the Synthesis subsection by clicking on the plus sign
(+) next to Synthesize.
You can now check your design by double-clicking on Check Syntax.
Ensure that any errors in your code are corrected before you continue. If the syntax
check succeeds, a green check mark will appear as shown
should be correct because both the HDL Bencher tool and ISE Simulator have already
checked for syntax errors. (When writing code, it is good practice to periodically check
your design for any mistakes using this feature.)
If you have just finished the schematic module, you will need to highlight the VHDL
