Abstract

PURPOSE:To reduce the manhour of preparation before simulation is started by selecting a necessary signal bus among plural real chip signal buses. CONSTITUTION:When a chip which is required for executing simulation is selected, a real chip signal bus control line 4 controls a real chip signal bus control part 1, connects only the signal bus of the required chip among the real chip signal buses 61-6n to an external signal bus 5. Then, signals are transferred between the chip and a simulator so as to execute simulation using the real chip. Since the signal bus of the chip required for simulation is selected among plural real chip signal buses 61-6n, the manhour of preparation can be reduced before simulation is started.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a real chip mounting system for a hardware simulator.

[Conventional technology]

Traditionally, this type of hardware simulator's real chip mounting method has been to mount one to one real chip on one real chip mounting board.
It was equipped with D real chips and was used by replacing the real chip mounting board or real chips as necessary.

[Problem to be solved by the invention]

The conventional real chip mounting method described above requires mounting the real chip, connecting the signal bins on the simulator side to the real chip, and wiring the power supply before starting the simulation. The disadvantage is that it requires a lot of man-hours.

[Means to solve the problem]

The real chip mounting method of the present invention includes a real chip signal bus control section, a real chip mounting section, a real chip power supply line, and a real chip signal bus control line in the real chip mounting method of a hardware simulator. , comprising an external signal bus and a plurality of real-chip signal buses, and selects a chip signal bus necessary for simulation from among the plurality of real-chip signal buses.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

The real chip mounting board 7 includes real chip signal buses 61 to 6n, real chip power supply lines 3. A real chip signal bus control line 4 and an external signal bus 5 are wired in advance between the real chip mounting sections 21 to 2n and the real chip signal bus control section 1. Chips are mounted on the real chip mounting parts 21 to 2n, and each chip is supplied with power and ground through a real chip power supply line 3.

When selecting a chip required for executing a simulation, control the real chip signal bus control unit 1 using the real chip signal bus control line 4 to select the necessary chip from among the real chip signal buses 61 to 6n. Only the signal bus of the chip to be used is connected to an external signal busler, signals are exchanged between the chip and the simulator, and a simulation using a real chip is executed.

Note that power is also supplied to chips that are not used in the simulation, but these chips are completely separated from the external signal bus controller by the real chip signal bus control unit 1, so no power is supplied to the chips that are operating. There are no negative effects.

〔Effect of the invention〕

As explained above, the present invention enables the selection of a necessary signal bus from a plurality of signal buses for real chips.
Since there is no need to mount a real chip, connect signal pins on the simulator side to the real chip, and perform power wiring before starting a simulation, there is an effect that the number of preparation steps before starting a simulation can be reduced. Furthermore, since a plurality of chips can be mounted on one real chip mounting board, the real chip mounting board can be shared.
