The following lists the Clock rules violation IDs. For a complete description of
these violations refer to the “Clock Rules” section of the Design-for-Test:
Common Resources Manual.
C1 — The netlist contains the unstable sequential element in addition to the
backtrace cone for each of its clock inputs. The pin data shows the value
that the tool simulates when all the clocks are at their off-states and when
the tool sets all the pin constraints to their constrained values.
C2 — The netlist contains the failing clock pin and the gates in the path
from it to the nearest sequential element (or primary input if there is no
sequential element in the path.) The pin data shows the value that the tool
simulates when the failing clock is set to X, all other clocks are at their off-
states, and when the tool sets all pin constraints to their constrained values.
C3 | C4 — The netlist contains all gates between the source cell and the
failing cell, the failing clock and the failing cell, and the failing clock and
the source cell. The pin data shows the clock cone data for the failing clock.
C5/C6 — The netlist contains all gates between the failing clock and the
failing cell. The pin data shows the clock cone data for the failing clock.
C7 — The netlist contains all the gates in the backtrace cone of the bad
clock input of the failing cell. The pin data shows the constrained values.
C8 | C9 — The netlist contains all the gates in the backtrace cone of the
failing primary output. The pin data shows the clock cone data for the
failing clock.
C10 — For pulse generators and clock procedures in DRC simulation, the
netlist contains an element that is clocked more than once.
C11 (FlexTest Only) — A scan shift clock must not have a non-return pin
constraint waveform (NR, C0, C1, CX, CZ). The default handling of this
violation is ERROR.
C12 (FlexTest Only) — A defined clock must not have a non-return pin
constraint waveform. The default handling of this violation is WARNING.
The following lists the Data rules violation IDs. For a complete description of
these violations refer to the “Scan Cell Data Rules” section of the Design-for-
Test: Common Resources Manual.
