6.1i TRCE - A path constrained by CLK is reported differently in the timing report and the timespec


A timing report on a design for one clock reports a path that is clocked from a different clock net. (This second clock net is independent from the first clock.)


In the 4.1i and newer software versions, if the clocks are independent, two clock period constraints are needed; the tools will not analyze between clock domains.
