OPTIMIZE_SSN
Controls the Simultaneous Switching Noise (SSN) optimization setting of the Fitter. This option
determines how aggressively the Fitter optimizes the design for SSN. If this option is set to 'Off', the Fitter
does not perform any SSN optimizations. If this option is set to 'Normal compilation', the Fitter performs
SSN optimizations which should not impact design performance. When this option is set to 'Extra effort',
the Fitter will perform aggressive SSN optimizations which may affect design performance.
