Vivado Constraints - Timing Constraints Editor is not available in Elaborated design
The menus "Window -> Timing Constraints" and "Tools -> Edit Timing Constraints" are not available in the Elaborated design.
They are only available in the opened Synthesized design and Implemented design.
Why is this?
The Timing Constraints Editor is disabled for the RTL analysis view by design.
It is only available in the Synthesis and Implementaion view.
