TIMING ADJUSTMENT METHOD AND APPARATUS FOR CLOCK TREE

Embodiments of the present disclosure provide a timing adjustment method and apparatus for a clock tree. The method comprises: configuring a plurality of driving units of different timings according to clock tree timing usage requirements of a chip, wherein target layouts of the plurality of driving units are the same; constructing a clock tree according to the plurality of driving units, and performing a timing check on the clock tree to obtain a timing check result; and when the timing check result is that a first target driving unit in the clock tree has a timing violation, replacing the first target driving unit with other driving units, wherein other driving units are driving units other than the first target driving unit among the plurality of driving units. The embodiments of the present disclosure can solve the problems in the related art that clock tree timing adjustment requires multiple placements & routings and thus consumes a lot of time and additional metal layer winding resources, thereby achie
