A standout feature detailed in this year’s guide is . The documentation outlines how the tool now dynamically swaps between different implementations of a logic block (e.g., switching from a complex AOI gate to a simpler NAND/NOR structure) based on the slack available. synopsys timing constraints and optimization user guide 2021
