Abstract
To provide a layout evaluating apparatus that can determine the feasibility of a layout from information only about a netlist, the layout evaluating apparatus is made to comprise a first individual index value generating unit for generating first individual index values, a second individual index value generating unit for generating second individual index values, a correlation extracting unit for generating an evaluation expression, which is an evaluation expression for calculating a second index value from the second individual index values and by which the second index value and its block size have a correlation, and a layout evaluating unit for identifying a range where the second index value and its block size have a correlation and for determining that a layout is possible if the first index value, which is obtained by substituting the first individual index values into the evaluation expression as a replacement for the second individual index values, is included in the correlation range.
