I had to apply additional constraints for clock placement for PRO ASIC3, though this was very long time ago. My advice is to dig into specific ProASIC3L documentation and/or ask Microchip FAE. He/She has access to factory database that has similar problems and resolutions. I think this is a shortest path to resolve this.

SpletCAD for VLSI 4 After Global Routing • The two-stage routing method is a powerful technique for routing in VLSI circuits. • During the global routing stage – The routing region is partitioned into a collection of rectangular regions. – To interconnect each net, a sequence of sub-regions to be used is determined. – All nets crossing a given boundary of a routing … SpletClock buffers, also known as global buffers (BUFG), are primitives that can take a regular signal as an input and connect to a clock net on the output side. The buffers have a high fan-out to minimize skew while driving the numerous other primitives that utilize the clock signal. Combinational logic shock epidemiology
