Abstract:
1. A net list creating method for structuring a target memory by using memory macro(s) previously arranged in each chip frame, the net list creating method comprising: a step of comparing a target word width directed to the target memory and a macro word width directed to the memory macro(s); a step of calculating a first word width ratio, the target word width to a maximum macro word width, and a first bit width ratio, a bit width of the target memory to a bit width of a memory macro that has the maximum macro word width, in case the target word width is larger than a maximum value of the macro word width; and a step of selecting a memory macro that has the maximum macro word width on condition that the first word width ratio is 2n (n: natural number) and the first bit width ratio is 2(−n) or lower, or selecting a memory macro that has a minimum composing number among a required number of memory macros calculated from a product of word width ratio and bit width ratio of the target memory to the memory macro in case the afore-mentioned condition is not satisfied.
