Note:  Found multiple reset signals.  This prevents
Automatic selection of a Global Reset Signal (GSR).
A possible cause is that the reset signal has multiple
top level net names by stitching through a lower level of hierarchy.
and then coming back up through another port.
An attribute of syn_hier="remove" on the module/architecture
will allow Synplify to merge the reset signals.

 Note: 'No paths' indicates there are no paths in the design for that pair of clock edges.
       'Diff grp' indicates that paths exist but the starting clock and ending clock are in different clock groups.
