Technical Field

The present invention relates to integrated circuit technology.

Background

There are many signals within the integrated circuit chip that need to be transmitted over long distances. The more common long-range signals are: a chip global control signal; a single-ended, differential, chip global clock; data of multiple bit (bit) width, address bus signals, etc. The chip global control signals include a module Enable (Power up or Power down) signal, a Reset (Reset) signal, and the like. The current common bit widths of data and address bus signals with multiple bit widths are 8bit, 16bit, 32bit, 64bit, 128bit and the like, and are used for data and address transmission among chip modules.

An intellectual property module circuit (generally, referred to as an IP core) is a circuit module that can be reused many times, and thus is generally used without modifying an IP core circuit. The IP core circuitry may be placed in different locations on the chip. Then, clock signals, data, address buses, etc. of the IP core circuitry and other blocks of the chip may come from (or go to) different directions of the IP core circuitry, and the chip interior may be represented by east, south, west, and north directions.

For a circuit module, the circuit module is sometimes used as an initiator of a signal (referred to as a "Master" for short) and sometimes used as a receiver of a signal (referred to as a "slave" for short).

Disclosure of Invention

The technical problem to be solved by the present invention is to provide an integrated circuit chip, which can realize the direction selection and driving of signal transmission.

The technical solution adopted by the invention is that the integrated circuit chip comprises at least 3 circuit modules, and is characterized in that at least two circuit modules are respectively connected with a direction driver, each direction driver is connected with a common connection point,

the direction driver comprises a signal transmission direction control unit, an enabling control unit and two external connecting ends, the signal transmission direction control unit is used for controlling the transmission direction of signals between the two external connecting ends, the enabling control unit is used for controlling the enabling state of the direction driver, and the signal transmission direction control unit and the enabling control unit are provided with control ends.

At least one of the circuit modules is an IP core module.

The present invention further includes a signal level compensation unit disposed between the two external connection terminals.

The circuit is very suitable for enhancing the driving capability of long-distance signals between modules in a chip, and can flexibly realize directional signal driving by enabling the control signal to control the direction of the signals.

The circuit can also realize the functions of one-direction input and multi-direction output.

The circuit is very suitable for integrating intellectual property module circuits (generally referred to as IP cores) in a chip. The signal lines in east, south, west and north directions in the chip are directly connected with the IP core circuit without modifying the IP core circuit.
