Slack is different after STA in Prime Time compared to PNR output due to timing optimizations and adjustments made during the Prime Time stage.

• During Prime Time, timing optimizations are performed to meet the required timing constraints, which may result in changes to the slack values.

• Prime Time stage involves detailed analysis and adjustments to improve timing closure, which can impact slack values.

• PNR output is the r...read more

To control congestion during placement activities, strategies such as proper floorplanning, utilization of congestion-aware placement algorithms, and iterative optimization can be implemented.

• Proper floorplanning to allocate enough space for critical paths and high-density areas

• Utilization of congestion-aware placement algorithms to minimize congestion hotspots

• Iterative optimization techniques to refine placement and a
