Message Type
Severity
Level
Meaning
SETUP WARNING Minimum time required for a data signal to be stable
prior
to the assertion of a
clock was not met.
HOLD WARNING Minimum time required for a data signal to be stable
after
the assertion of a
clock was not met.
RELEASE WARNING Minimum time required for a signal that has gone inactive (usually a control
such as CLEAR) to remain inactive before the asserting clock edge was not met.
WIDTH WARNING Minimum pulse width specification for a signal was not satisfied; that is, a pulse
that was too narrow was observed on the node.
FREQUENCY WARNING Minimum or maximum frequency specification for a signal was not satisfied.
Minimum frequency violations indicate that the period of the measured signal is
too long, while maximum frequency violations describe signals changing too
rapidly.
GENERAL INFO Boolean expression described within the GENERAL constraint checker was
evaluated and produced a
true
result.
