LOGIC SIMULATOR

PURPOSE:To interrupt/resume simulation by designating description information when simulation is executed through the use of a hardware description language. CONSTITUTION:A construction information output means 11 outputs construction information (c) on hardware, and an operation information output means 12 outputs operation information (d) on hardware. A line information output means 13 adds line information to operation information (d). An execution control means 14 processes execution information included in the operation information (d). An interruption control means 15 refers to interruption information (e) when the execution control means 14 detects line information on operation information (d), controls the interruption/resumption of simulation, rewrites/refers to interruption information (e) and displays the hardware description language (b) of an interrupted place. A command control means 16 executes the command of a simulator by the instruction of the interruption control means 15. Thus, simulation can be interrupted/resumed.
