Check for Errors and Warnings
After performing a code generate, check the status bar at the bottom
of the Project Management window. The status bar indicates whether
or not a .L2P file was successfully generated.
If a .L2P file was not created, check the Hardware Management
Window to view the errors and/or warnings compiled during the
process of code generation.
The window below shows an example of code generation warnings.
