WebbEnd-cap cells are preplaced physical-only cells required to meet certaindesign rules and placed at the ends of the site rows by satisfying well tie-off requirements for the core rows. These library cells do not have any signal connectivity. They connect only to the power and ground rails once power rails are created in the design.

WebbSolution. The Physical Synthesis phys_opt_design command performs timing-based logic replication of high-fanout drivers and critical-path cells. Drivers are replicated, then loads are distributed among the replicated drivers, and then the replicated drivers are automatically placed. This optional command is run after placement and before routing.
