6.2 Hint 2 - Use Default Properties and Strategies

The default properties and strategies used ty the fitter are selected to achieve the best fit for the design into the ATF15XX/ATF1500 device. Users may customize properties and strategies to meet specific design requirements, as described in FIT1500 and FIT15XX Options and Strategies . However, customizing fitter behavior constrains how the design is mapped and may result in a suboptimal fit. For additional information, refer to Design Passes.
