Using TNM to create Groups.

NET clock TNM=clk_group;

• These timing groups can overlap, meaning a FFS, LATCHES, RAMS, or PADS can belong to multiple groups if necessary to describe your design’s timing

• Time constraints are case sensitive (TNM=abc ? TNM=ABC)

• Groups are ideal for identifying groups of logic that work at different speeds…….(multi-cycle paths and other slow exceptions).
