Abstract
The electronic circuits of a large-scale ASIC or logic device are assigned to a plurality of programmable chips with logic block division that enables the finished circuits to operate at appropriate timings. A logic division processing unit divides the electronic circuits into a plurality of groups for automatic assignment to a plurality of programmable chips. A checking unit determines whether the designated logic blocks are accommodated in one programmable chip, and a division processing unit determines which logic blocks are to be assigned and the order of assignment priorities when the designated logic blocks are not all accommodated in the same programmable chip.
