Hi All,
Can anyone tell me what are all the flow/design metrics can be collected from the following stages?.

1. FloorPlan
2. Placement
3. Ideal Clock IPO
4. CTS
5. Post-CTS IPO
6. First Routing

Please help me by providing some inputs.
 

1. FloorPlan
Utilization
Slack with zero interconnect delay
2. Placement
Timing numbers,utilization,repeater count,VT percentage,cong,cell density,useful skew,clock gate placement(if any),cell hierarchy,cells in the macro channels
3. Ideal Clock IPO
Same as placement
4. CTS
clock latency,global skew, local skew,CT cell count change and change in area, any combo cells or mix vt cells in the clock path,clock tree topology + metrics collected for placement
5. Post-CTS IPO
Same as CTS
6. First Routing
drc count, drc hot spots match with cong map hot spots,filler cell insertion and metrics collected during placement

@itsmeteja,
Thanks alot for the detailed reply..

Do you think these metrics are enough to qulify the quality of the flow/script?.
 

i feel,, at each and every stage,, timing analysis is required
