The EDGE command allows you to specify the edge recognizer term for
the timing analyzer trigger on a per !abel basis. Each command deals with

specification could require several commands. The edge specification
uses the characters R, F, T, X to indicate the edges or don't cares as
follows:
R = rising edge
F = falling edge
T = toggling or either edge
X = don't care or ignore the channel
The position of these characters in the string corresponds with the
position of the channels within the label. All channels without "X" are
The EDGE query returns the edge specification for the specified label.
