The timing results from report_timing are based upon new timing delay name associated with the BEL (basic element) instead of COMP (component) based in trce/timing analyzer (twr).
These new timing delay names are more descriptive and easier to understand.
The new timing delay names follow the following format:
1. Timing arc type: Propagation (Prop) delay, Setup (Setup),Hold (Hold), Min Period (Minper)
2. Cell Name: LUT, Carry, fdre, ramb36e1, etc.
3. Source Pin: A1, O1, D, etc.
4. Destination Pin: O, C, etc.
