ID:170038 Cannot place following RAM cells or portions of RAM cells -- a legal placement which satisfies all the RAM requirements could not be found

CAUSE: You created assignments, or assignments were automatically created by the Fitter; however, these assignments constrained the placement of entities so that the Fitter cannot place the RAM cells to meet design requirements, or the design requires more RAM than the device contains. As a result, the RAM cells or portions of RAM cells listed below this message have conflicting assignments. This message is a submessage of the message that precedes it in the Messages window and in the Messages section of the Report window.

ACTION: Refer to the action of the original message. Click the + icon to expand the list of RAM cells or portions of RAM cells that cannot be placed in the device.
