Title: Automatic arrangement method
Inventor: ARAKAWA KOICHI
IPC: H01L21/82
Filed: 1992-04-23
Abstract: PURPOSE:To obtain an arrangement result having a short estimated total connec tion line length by accurately evaluating connection line length to be an evalua tion function for dividing processing in an automatic arrangement method for executing arrangement by repeating dividing processing. CONSTITUTION:Dividing processing consists of initial dividing processing 101, gain initializing processing 102, division improving processing 103, and divided result writing 104. An evaluation value of a divided state is the sum of the estimation values of a connection line obtained by correcting the half peripheral length of a minimum included rectangle including the end points of the connection line by the number of end points. In cell movement and gain updating processing 109 for respective processing 102, 103, a change in the length of the connection line at the time of moving cells can rapidly be found out by sorting cell distribution.
