PROBLEM TO BE SOLVED: To provide a logic simulation device which can accurately perform logic simulation even the delay time of each cell is different according to the state of the cell behind the above cell. SOLUTION: If the state of the logic element following one logic element affects the delay time of the logic element, the state of the following logic element is transmitted to the logic element because of the virtual connection relation on a virtual connection between the logic element and following logic element. The virtual connection relation is connection relation which is not physically present and connection relation used only in logic simulation. Consequently, the state of the following logic element can be reflected on the delay time of the delay element and more accurate logic simulation can be carried out.
