1.9.3.2. Multiple Clock Domains

The Synplify software can perform timing analysis on unrelated clock domains. Each clock group is a different clock domain and is treated as unrelated to the clocks in all other clock groups. All clocks in a single clock group are assumed to be related, and the Synplify software automatically calculates the relationship between the clocks. You can assign clocks to a new clock group or put related clocks in the same clock group with the Clocks tab in the SCOPE window, or with the define_clock attribute.
