Scan path circuit permitting transition between first and second sets of check data |
摘要 |
Logical device comprises a combinational circuit and a sequential circuit. The sequential circuit has a holding means which is between the combinational circuit and flip-flops of the sequential circuit. The output data of the holding means are not changed until a control signal is applied to a control terminal. The performance of the combinational circuit in the logical device can be checked.
