摘要： PROBLEM TO BE SOLVED: To provide a logic emulator which avoids flow of an excessively large current, to prevent external devices and the logical emulation device from being damaged, thereby smoothly verifying the circuits under test. SOLUTION: An output control circuit 27 acquires detected temperature data of variable logic elements 20, 21 by temperature detector units 10, 11, and sets the logic elements 20, 21 to high output impedance states, when excessively large currents flow in the logic elements 20, 21 to excessively raise their temperatures. This avoids collisions of signals between the logic elements 20, 21 and collision of signals between each logic circuit 20, 21 and an external device 1, thereby preventing excessively large currents from continuously flowing in the logic elements 20, 21 and the external device 1.

摘要： PROBLEM TO BE SOLVED: To solve the problem that it is difficult to know correlation between malfunction and instability in a power source due to insufficiency of means for observing the instability in the power source inside a system LSI although one of causes of malfunction of the LSI is instability of internal power supply voltage and the tendency gets further worse due to speedup and reduction in voltage in recent years.
SOLUTION: A circuit for generating a trigger signal when a fluctuation of the power source at each functional block power supply terminal position inside the system LSI exceeds a certain amount is constituted by resistive voltage division and incorporation of a comparator. By inputting the trigger signal into an internal signal observation control circuit of the system LSI, respective internal states during the fluctuation of the power source are output to the outside of SOC.
