T4 — The netlist contains all the gates in the backtrace cone of the clock inputs of the blocked gate. The pin data shows the values the tool simulates for all time periods of the shift procedure.

T5 T6 — The netlist contains all the gates in the backtrace cone of the clock inputs of the blocked gate. The pin data shows the values the tool simulates for all time periods of the shift procedure.

T7 — The netlist contains all the gates in the path between the two failing latches. The pin data shows the values the tool simulates for all time periods of the shift procedure.

T11 — A clock input of the memory element closest to the scan chain input must not be turned on during the shift procedure prior to the time of the force_sci statement.

T16 — When clocks and write control lines are off and pin constraints are set, the gate that connects to the input of a reconvergent pulse generator sink gate (PGS) in the long path must be at the non-controlling value of the PGS gate.

T17 — Reconvergent pulse generator sink gates cannot be connected to any of the following: primary outputs, non-clock inputs of the scan memory elements, ROM gates, non-write inputs of RAMs and transparent latches.

T18 — The maximum traced number of cells in the longest scan chain of a group must equal the entered number of repetitions in the apply shift statement in the load_unload procedure.

T19 — If a scan cell has a SLAVE, then all scan cells must have a SLAVE.

T20 — The number of shifts specified using the Set Number Shifts command must be at least equal to the length of the longest scan chain.

T21 —The number of independent shift applications in the load_unload procedure must be less than the scan chain length.

T22 —If the rules checker traces a scan cell during the application of an independent shift, it must also trace that cell during the application of its associated general shift.

T23 —The chain length calculated for an independent shift must be the same as that calculated for its associated general shift.
