Error (170025): Fitter requires that more entities of type <cell type> be placed in a region than are available in the region - Error (170025): Fitter requires that more entities of type <cell type> be placed in a region than are available in the region Description Due to a problem is the Quartus® II software version 12.1 and later, you may see this error if the fitter has promoted a high fan-out clock to a regional clock instead of a global clock. The error occurs because the region which is defined by the regional clock is too small to pack the logic that uses the particular clock. Resolution To work around this problem, manually promote high fan-out clocks to use global clock networks using the GLOBAL_SIGNAL assignment.
