Embodiment Construction
[0097] Hereinafter, the present invention will be further described in detail with reference to specific embodiments and the drawings of the specification.
[0098] Reference Figure 7 , Is a flowchart of the timing budget method considering distance and clock of the present invention. The present invention includes the following steps:
[0099] The first step is to determine the process node and the metal layer used. For a given process and metal layer, using a repeater insertion method can make the interconnection delay linearly related to the length of the interconnection line. The interconnection delay per unit length α can be obtained by the following calculation method.
[0100] 1.1 Obtain the process node and the total number of metal layers M max .
[0101] 1.2 Select section And The layer metal serves as the horizontal and vertical wiring metal layer. among them For right Rounding, For right The rounding.
[0102] 1.3 Get the first And The parasitic resistance r pe...
