Syntax set_max_skew [-h | -help] [-long_help] [-fall_from_clock <names> ] [-fall_to_clock <names> ] [-from <names> ] [-from_clock <names> ] [-get_skew_value_from_clock_period <src_clock_period|dst_clock_period|min_clock_period> ] [-rise_from_clock <names> ] [-rise_to_clock <names> ] [-skew_value_multiplier <multiplier> ] [-to <names> ] [-to_clock <names> ] [ <skew> ]
Arguments -h | -help Short help
-long_help Long help with examples and possible return values
-fall_from_clock <names> Valid source clocks (string patterns are matched using Tcl string matching)
-fall_to_clock <names> Valid destination clocks (string patterns are matched using Tcl string matching)
-from <names> Valid sources (string patterns are matched using Tcl string matching)
-from_clock <names> Valid source clocks (string patterns are matched using Tcl string matching)
-get_skew_value_from_clock_period <src_clock_period|dst_clock_period|min_clock_period> Compute skew constraint as a multiple of the clock period
-rise_from_clock <names> Valid source clocks (string patterns are matched using Tcl string matching)
-rise_to_clock <names> Valid destination clocks (string patterns are matched using Tcl string matching)
-skew_value_multiplier <multiplier> Value by which the clock period should be multiplied to compute skew requirement
