In the Optimize tab, you can select one of two Optimization types: Area and Delay. Altera recommends that you perform an area optimization first, and then a timing optimization later. You can also select from one of four "Passes" under Extended Optimization Effort.
Note: In the Optimize tab, you can also specify to preserve or flatten the hierarchy in the output netlist, well as adding I/O pads to the design. By default, the LeonardoSpectrum software preserves hierarchy in a design. To ensure the fastest possible run times, the netlist is "flattened," which means that all common sub-blocks reference a single view or netlist. The LeonardoSpectrum software optimizes the netlist only once. When you want to optimize two different instances of common sub-blocks, the netlist must be unfolded. For example, you can optimize one block for area and a second block for delay.
Click Apply.
To generate a report on the results of area and timing optimizations with the Mentor Graphics LeonardoSpectrum software:
Click the Report tab.
To generate a report on the area optimization results, at the bottom of the Report tab, click the Report Area tab.
To generate a report on the timing optimization results, at the bottom of the Report tab, click the Report Delay tab.
If necessary, in the appropriate tab (either Report Area or Report Delay), specify the appropriate settings for your report.
