Use create_macro to create a new macro object. Macro names must be
unique. If you attempt to create a macro with the same name as an existing macro,
the tool generates an error.
create_macro Syntax
create_macro <name>
create_macro Example
create_macro m0
Creates a macro object named m0.
Tip: To ensure optimal LUT-FF
alignment, specify the BEL location when creating your macro. Set the BEL location
separately as a property on the cell objects.
