placement constraints. The button displayed reflects the currently selected
mode:
- Create BEL Constraint Mode

being placed. This fixes the cell to the specified BEL within
the slice.

- Assigns a LOC placement constraint to the cell
being placed. This fixes the cell to the specified slice but
allows the cell to use any available BELs within the slice.
