3.1/3.2 EDK- When using XFLOW in XPS, MicroBlaze/PowerPC System generated by PlatGen instantiates IBUFG, but there is no BUFG inferred for system clock


Keywords: EDK, EST, PlatGen, XFLOW, local, clock, resources, BUFG, IBUFG, BUFGP, MicroBlaze, PowerPC

Urgency: Hot

General Description:
The MicroBlaze/PowerPC systems generated by PlatGen instantiate an IBUFG, and this results in the processor system clock using local resources to route the clock.


This problem is fixed in the latest 3.2 EDK Service Pack, available at:
The first service pack containing the fix is 3.2 EDK Service Pack 1.

PlatGen now instantiates a "BUFGP" as the combination of IBUFG and BUFG.
