PURPOSE:To use simultaneously plural emulators which are so far used individually by attaining the stop of each emulator synchronously with one emulator. CONSTITUTION:Signals a-c are supplied to terminals a-c respectively when the emulation is carried out with a multi-emulator. In such a case, the terminal (b) is set at 1 at first and gates G1 and G3 are open owing to an emulation mode. Then a signal which breaks the emulator is supplied in an active high state and triggers a monostable multivibrator circuit M1 to produce pulses in periods t1- t2 which are set at active low levels at an output. This emulator is broken together with other emulators constituting the multi-emulator through an open collector type buffer circuit G4. |
