AMD Adaptive Computing tools offer a number of options and settings that provide a trade-off between design performance, resource usage, implementation runtime, and memory footprint. The settings that produce the best results for one design might not necessarily work for another design.
For the purpose of the FMAX Margin System Analysis, the IP design is characterized with default settings without specific constraints (other than the clocking constraint). This analysis is done with all different FPGA architectures and the maximum speed grade.
