Semiconductor device and designing method of the same |
摘要 |
A semiconductor device includes: a control target circuit section; and a voltage control section configured to dynamically control a supply voltage to the control target circuit section. The control target circuit section includes: a delay monitor circuit configured to measure a delay in the control target circuit section as a monitor delay; and a target delay register configured to store a target delay data which shows a target delay as a target value of the monitor delay. The delay monitor circuit compares the monitor delay and the target delay shown by the target delay data and sends a comparison resultant signal to the voltage control section to show a result of the comparison. The voltage control section controls the supply voltage based on the comparison resultant signal such that the monitor delay approaches to the target delay.
