Incremental Optimization | Quartus® Prime Design Software - Incremental optimization offers a fast methodology to converge to design sign-off. More control over the flow is provided in the fitter stage. Product Pages Broadcast Consumer Industrial Test Wireline Medical Aerospace, Defense, and Government Transportation Access Wireless Data Center Cloud Networking Incremental Optimization Incremental Optimization with the Quartus Prime Pro Edition The incremental optimization capability in the Quartus® Prime Design Software Pro Edition software offers a fast methodology to converge to design sign-off. The traditional fitter stage is divided into finer stages for more control over the flow in the Quartus® Prime Pro Edition software: Plan stage allows legal placement and clock planning, along with timing analysis on preliminary I/O and HSSI to FPGA fabric transfers Placement stage enables timing analysis before proceeding to the Route stage. The Placement stage is split into an Early Placement stage and a final placement stage: Perform timing analysis after the Early Placement stage while the rest of the flow is still running Chip planner provides a visual view of the Early Placement stage Route is split into Route and Post-Route stages for faster design convergence. 3-corner timing analysis after route and 4-corner timing analysis after post-route reduces compile time. The post-route stage offers an Engineering Change Order (ECO)-like flow where setup and hold failures are automatically fixed, thus reducing compile time. High-speed or low-power tile optimization is performed in the Post-Route stage.
