Abstract
Disclosed is a method for designing a semiconductor device so as to prevent the device from being broken even when memory circuits are reset. This method is executed using a computer as follows. First, the computer groups the memory circuits arranged on the basis of arrangement information. Then, the computer inserts a delay circuit between reset lines such that the reset timing of the memory circuits is different in each group. Therefore, the reset timing is different in each group. As a result, a large current flowing during reset is controlled to suppress AC noise so that the semiconductor device can be prevented from being broken.
