Recommended DSE Settings for HardCopy Stratix Designs
The HardCopy Stratix design does not require all advanced settings or
effort-level settings in DSE. Altera recommends using the following
settings in DSE for HardCopy Stratix designs:
■ In the Settings tab (Figure 6–2), make the following selections:
● Under Project Settings, enter several seed numbers in the Seeds
box. Each seed number requires one full compile of the
HardCopy Stratix project.
● Under Project Settings, select Allow LogicLock Region
Restructuring.
● Under Exploration Settings, select Search for Best
Performance, and select Low (Seed Sweep) from the Effort
Level menu.
■ Turn on Archive all Compilations (Options menu).
After running DSE with the seed sweep setting, view the results and
identify which seed settings produced the best compilation results. Use
the archive of the identified seed, or merge the compilation settings and
seed number from the DSE archived project into your primary HardCopy
Stratix project.
