ABSTRACT:
A semiconductor integrated circuit device having a control signal system for avoiding failure to check an indefinite signal propagation prevention circuit, for facilitating a check included in an automated tool, and for facilitating a power shutdown control inside a chip. In the semiconductor integrated circuit device, power shutdown priorities are provided by independent power domains (Area A to Area I). A method for preventing a power domain having a lower priority from being turned OFF when a circuit having a high priority is turned ON is also provided.
