General Description: A problem has been seen involving the use of a single F6MUX which is packed into a slice with RAM. Map creates a route-thru using the F6MUX in another slice and the F5MUX in the same slice as the original F6MUX.
The placer then complicates matters by assembling a RAM macro that contains only half of the F5/F6 route-thru mux pair. This leads to the following error later in placement:
ERROR:Place:1802 - Components asio1/uart2681/baud1/preload_value.I_51_f5_f6_I0_rt_sig and asio1/uart2681/baud1/load_value_2_[4] are using the F5/F6MUX resources. The components should be in a single common RPM. One component is not in the RPM.
