Description

Adapter, data transmission system and method

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an adapter, a data transmission system, and a data transmission method.

Background

To meet the increasingly complex chip design requirements, the scale of chip design has also grown dramatically. The hardware acceleration simulation (English full name: Emulation) is used as a new technology of chip verification, and has the advantages of high compiling speed, large capacity, strong fault eliminating capability and the like. In the Emulation application, there is a widely used online Emulator (ICE) mode, which can compile a Design to be verified (DUV) into a hardware Emulation tool (evl) and connect with an external target device for verification.

At present, because an Emulator generally operates at a frequency below 4 megahertz (MHz) in an ICE mode, while an operating frequency of an external target device may reach hundreds of MHz, and two sides of the external target device cannot be directly connected with different speeds, a speed adapter is required to convert the speed, specifically, as shown in fig. 1, fig. 1 is a schematic diagram of a hardware simulation tool directly connected with the speed adapter in the prior art, wherein a dedicated cable is adopted between the Emulator S1 and the speed adapter S2, the Emulator cables of different manufacturers may be different, and a connection line between the speed adapter S2 and the external target device S3 may select an optical fiber or a cable according to the difference of the speed adapters.

However, because an Emulator is expensive and scarce in resources, in order to better develop its value, resources of the Emulator may be time-multiplexed by a plurality of items, as shown in fig. 2, fig. 2 is a schematic diagram of a time-multiplexing hardware simulation tool in the prior art, 3 rate adapters shown in the diagram are only one schematic diagram, and the rate adapters may be connected to the Emulator through at least one cable, target devices connected to different items may be different, which requires different rate adapters to be connected to the Emulator. However, the number of parallel cables provided by the Emulator is limited, and each cable outputs at least one set of data, and if a new target device needs two sets of data provided by the Emulator at the same time, the target device needs to be switched by manually plugging and unplugging the cables, that is, the cables corresponding to the two sets of data are unplugged, and then the new target device is plugged in. However, the manual plugging and unplugging of the cables can reduce the switching efficiency and increase the labor cost, and meanwhile, frequent plugging and unplugging of the cables can also cause hardware faults, so that the hardware test automation is difficult to realize.
