General Description: The placer fails with the following error:
ERROR:Place:1781 - A global clock component <I$117> configured as a selectable mux is placed in site BUFGMUX7P. This configuration requires that the global clock site BUFGMUX6S be empty in order to route up both of the inputs. The site BUFGMUX6S has the global buffer <I$204> placed there. This design is unroutable. Please correct this problem before continuing.
