摘要

When a sequential circuit to which a clock signal distributed by a first buffer included in a clock distribution circuit is input is added, in a case where a plurality of other sequential circuits are connected to the first buffer, a processor determines whether or not a distance between the sequential circuit to be added and the first buffer is between a maximum value and a minimum value of distances between the first buffer and the plurality of other sequential circuits based on the physical design data stored in the memory, and, as a result of the determination, in a case where the distance between the sequential circuit to be added and the first buffer is between the maximum value and the minimum value, the processor performs wiring processing of the clock signal supplied from the first buffer for the sequential circuit to be added.

1. A design support device comprising:
a memory configured to store physical design data of a circuit that includes a clock distribution circuit having a buffer; and a processor, wherein the processor, when a sequential circuit to which a clock signal distributed by a first buffer included in the clock distribution circuit is input is added, in a case where a plurality of other sequential circuits are connected to the first buffer, determines whether or not a distance between the sequential circuit to be added and the first buffer is between a maximum value and a minimum value of distances between the first buffer and the plurality of other sequential circuits based on the physical design data stored in the memory, and wherein, as a result of the determination, in a case where the distance between the sequential circuit to be added and the first buffer is between the maximum value and the minimum value, the processor performs wiring processing of the clock signal supplied from the first buffer for the sequential circuit to be added.
