Abstract
The temperature of the circuit to be verified is evaluated. A simulation executing section (101) executes logic simulation of the circuit to be verified expressed in function block units at function block level. A circuit action extracting section (103) extracts an actin mode of a function block in its process. A total current consumption calculating section (105) calculates the total current consumption which is the current consumed in the entire circuit to be verified, on the basis of the data of current consumption in each action mode and extracted action mode. An average current calculating section (107) calculates the average current which is the average of the total current consumption over the check period, reflecting the thermal characteristic of the circuit to be verified. An allowable temperature judging section (109) calculates the temperature of the circuit to be verified according to this average current, and compares with an allowable current. An error message output section (110) issues a message when the temperature exceeds the allowable temperature. The temperature can be evaluated, therefore, by using logic simulation. (FIG. 1)
