ANALYZE_LATCHES_AS_SYNCHRONOUS_ELEMENTS
Directs the Timing Analyzer to analyze latches as synchronous elements, rather than as combinational
elements. Although latches continue to be implemented as a LUT feeding back onto itself, turning on this
option directs the Timing Analyzer to analyze all latches as synchronous elements. Specifically, the clock
enable is analyzed as an inverted clock. The Timing Analyzer reports the results of setup and hold analysis
on these latches
