OPTIMIZE_TIMING
Controls whether the Fitter optimizes to meet the maximum delay timing requirements (for example,
clock cycle time). By default, this option is set to Normal compilation. Turning it off can help fit designs
that have extremely high interconnect requirements and can also reduce compilation time, although at the
expense of significant timing performance (since the fitter will be ignoring the design's timing
requirements). If this option is off, other fitter timing optimization options have no effect (such as
Optimize Hold Timing).
