 Report_annotated_delay 

• Annotated delay means To set cell/net delay.
• To set a cell delay, specify the delay from a cell input to an output of the same cell. 
• To set a net delay, you specify the delay from a cell output to a cell input.
• In a design that uses SDF-annotated delays on all arcs or almost all arcs, such as 95% or more
• Annotated delay Means  :RC values are applied properly 
• Non -Annotated Delay means: RC values are not applied properly 
• For any arcs that are not annotated, Sign-off Tool  estimates the delay and output slew using the best available input slew. 
• For a block of arcs that are not annotated, Tool propagates the worst slew throughout the block.
