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.
