Setup Slack Optimization techniques at Placeopt stage
When it comes to timing optimization techniques, there are many techniques present but it depend on the stage in ASIC Physical Design flow. fixing methods and timing recipes are different at different stage. generally timing methods should be applied based on the stage i.e. one fixing method might be valies for timing fix but it can't be applied to all the stages. Timing Fixing techniques at Placeopt stage Timing fixing methods at the Placeopt stage can be broadly categorized into two main approaches: Automatic Tool-Based Techniques : all EDA tools can perform automated optimizations, such as buffer insertion, cell resizing, and high fanout net (HFN) optimization, which helps in timing optimization. Manual Timing Fixing Methods : These involves user -driven adjustments on top of the EDA default optimization. Lets discuss both techniques in detail. Automatic Tool-Based Techniques : Buffer insertion : generally inserting buffer on long net helps to reduce ove...
