    摘要: A semiconductor integrated circuit device is provided, the circuit being capable of arranging a control signal system, avoiding a danger of failure to check an indefinite signal propagation prevention circuit or the like, further facilitating a check oriented to mounting on an automated tool, and facilitating power shutdown control inside of a chip. In the semiconductor integrated circuit device, power shutdown priorities are provided by independent power domains Area A to Area I. A rule is provided, the rule defining that, in the case where a circuit having a high priority is turned ON, a power domain having its lower priority cannot be turned OFF, thereby facilitating a designing method. In addition, areas capable of applying still another power supply are provided in the independent power areas Area A to Area I. In that area, a relay buffer (repeater) and a clock buffer or an information retaining latch for saving information are integrated. A layout may be provided in a direction vertical to a direction in which cells are arranged in a row direction for the purpose of dispersing a current of a light supply line.

    摘要: There is a need to ensure operation performance of a circuit region under DVFS control at low costs and highly precisely while a power-supply voltage change is made to the region. A first circuit (FVA) uses a first power-supply voltage (VDDA) for operation. A second circuit (NFVA) uses a second power-supply voltage (VDDB) for operation. A clock delay may be adjusted between paths for transmitting a clock to these circuits. When VDDA equals VDDB, a clock is distributed to FVA through a path that does not contain a delay device for phase adjustment. When the power-supply voltage for the FVA region is reduced, a clock is distributed to the FVA region based on a phase equivalent to one or two cycles of the clock displaced. Synchronization control is provided to synchronize clocks (CKAF and CKBF) and ensures operation so that a phase of two clocks to be compared fits in a range of design values while the power-supply voltage for the first circuit is changed.

    摘要: A scan chain configuration and a control method for the same are provided, which are optimized for the leakage current reduction technique by a vector input in SoC in which many functional blocks are mounted. The semiconductor integrated circuit includes: plural power domains (Area1-AreaN) which have plural functional blocks; power switches (PSW1-PSWN) which can supply a power source for operation to the power domains; a scan chain provided for every power domain, and a memory unit (VEC) which supplies, to a scan chain, a vector to enable shifting to a low-leakage state. By re-coupling the scan chain only to a non-operating functional block, it is possible to perform shifting to a low-leakage state for a short time.

    摘要: In a semiconductor integrated circuit wherein low-threshold-voltage and high-threshold-voltage transistors are disposed mixedly, the operating speed of each transistor can be properly controlled in speed control execution through regulation of a power supply voltage VDD. The semiconductor integrated circuit comprises an internal circuit and measuring circuits. The internal circuit comprises a low-threshold-voltage MOS transistor and a high-threshold-voltage MOS transistor, and the degree of threshold voltage variation of the low-threshold-voltage MOS transistor is larger than the degree of threshold voltage variation of the high-threshold-voltage MOS transistor. The measuring circuit detects which one of fast, typical, and slow states is taken by both the low-threshold-voltage MOS transistor and the high-threshold-voltage MOS transistor. When the result data detected indicates the fast state, the power supply voltage VDD is set to a lower power supply voltage level “VDD−ΔVDD” corresponding to a small variation gradient “β[V/σ]”. When the result data detected indicates the typical state, the power supply voltage VDD is set to an intermediate power supply voltage level “VDD±0”. When the result data detected indicates the slow state, the power supply voltage VDD is set to a higher power supply voltage level “VDD+ΔVDD” corresponding to a large variation gradient “α[V/σ]”.
