Embodiment Construction

[0026] figure 2 It is a block diagram of a circuit simulation system with programming function in the present invention. Such as figure 2 As shown, it includes a system power supply device 210 , a DC-to-DC converter 220 , a processing device 250 , a programming socket 230 , a connecting device 260 , a timing generating device 240 , and a transmission module 270 .

[0027] The system power supply device 210 generates a first DC voltage V as the working power of the circuit simulation system. The first DC voltage is preferably 5 volts. The DC-to-DC converter 220 is coupled to the system power supply device 210, and converts the first DC voltage into a second DC voltage V DD and a third DC voltage V PP , so as to provide the DC high voltage required for programming an integrated circuit 280 . where the second DC voltage V DD and the third DC voltage V PP The voltage value of is greater than the voltage value of the first DC voltage V. The second DC voltage V DD is pref...

Abstract

This invention relates to a circuit simulation system with a replication function including: a system power supply device, a DC-DC converter, a process device, a replication base and a connection device, in which, the supply device generates a first DC voltage, the DC-DC converter converts the first DC voltage to a second and a third DC voltage, the process device includes a processor and a parallel / serial converter. When the processor carries out the replication function, it generates a replication signal by converting replication codes with the parallel / serial converter, the replication basereceives the replication signal, the second and third DC voltages to reply the IC plugged on it, one end of the connection device is connected to the process device and the other is connected to thetarget board to drive and receive electric signals of the target board when simulating circuits.

Description

technical field [0001] The invention relates to the technical field of integrated circuit programming and circuit emulation (in circuit emulation, ICE), in particular to a circuit emulation system with a programming function. Background technique [0002] figure 1 is a block diagram of a known general-purpose programmer. Such as figure 1 As shown, it includes a control logic unit 105, a storage device 110, a transmission interface 115, a peripheral IO interface 120, a microprocessor 125, a programming socket 130, a system power supply device 135 and a DC to DC Converter 140. When programming an integrated circuit 160 , the user first inserts the integrated circuit 160 on the programming socket 130 . Then download a programming code from a personal computer 150 to the microprocessor 125 via the transmission interface 115 , and store it in the storage device 110 . Afterwards, the microprocessor 125 generates a specific control signal according to the programming code, and...
