Description
Create a macro for the relative placement of cells.
Macros are primarily used to place small groups of associated cells together to improve resource efficiency and enable faster interconnections. The create_macro command lets you define macros in an open synthesized or implemented design for relative placement by place_design, like RPMs defined by the RLOC constraint in RTL source files. Refer to the Vivado Design Suite User Guide: Implementation (UG904) for more information on defining relatively placed macros.
After creating the macro, specific cells can be assigned to the macro using the update_macro command. To change a currently defined macro, you must delete the macro with delete_macro, recreate the macro, and update the macro with the new contents. You cannot simply overwrite an existing macro.
Use delete_macro to delete a defined macro. Use get_macros to return a list of currently defined macros in the design.
This command operates silently and does not return anything.
