ABSTRACT:
The present invention provides a method to balance a clock tree dynamically. A controllable buffer is inserted in a specific level of a clock tree, and a controller is provided for adjusting two clocks with different skew by controlling the PMOS/NMOS arrangements in the controllable buffer so as to generate more current for compensating the time delay of slow clock to a sink. This method effectively suppressed the clock skew generated by the voltage drop or the temperature variations in the synchronous logic circuit design.
