Embodiment 1

[0039] image 3 A flowchart of the realization of the verification method of the conversion controller provided by Embodiment 1 of the present invention is shown. The method is based on the Verification Methodology Manual (Verification Methodology Manual, VMM) verification platform, and is described in detail as follows:

[0040]In step S301, data related to the transaction is obtained according to the transaction describing the DMA bus operation, and a control transaction is generated from the transaction and the obtained data.

[0041] In step S302, monitor the DMA bus sequence received or sent by the conversion controller, analyze and obtain the control information in the bus sequence as the control information of the monitoring transaction, and read from the pre-stored data related to the AXI bus address read and write according to the control information. The data corresponding to the control information is taken as the data information of the monitoring transaction.

Embodiment 2

[0047] Figure 4 A flow chart of the realization of the verification method of the conversion controller provided by Embodiment 2 of the present invention is shown. The method is based on the Verification Methodology Manual (Verification Methodology Manual, VMM) verification platform, and is described in detail as follows:

[0048] In step S401, a transaction describing DMA bus operation is generated, and the transaction includes control information and data information.

[0049] In the embodiment of the present invention, a transaction is a description of a DMA bus operation to be sent to a DMA bus to AXI bus conversion controller, for example, a bus operation may be a read operation or a write operation.

[0050] In step S402, according to the transaction describing the DMA bus operation, generate a DMA bus operation conforming to the timing of the DMA bus, and send the DMA bus operation to the DMA bus to AXI bus conversion controller.

[0051] In step S403, the AXI module ...

Embodiment 3

[0062] Figure 5 A structural diagram of a verification system for a switching controller provided in Embodiment 3 of the present invention is shown. The system is based on a VMM verification platform. For ease of description, only parts related to the embodiment of the present invention are shown.

[0063] The embodiment of the present invention carries out verification system from the conversion of DMA bus to AXI bus conversion controller and comprises:

[0064] Data related to reading and writing of AXI bus addresses stored in memory 51 in advance.

[0065] In the embodiment of the present invention, the memory is a memory in the form of a register. Since the address of the AXI bus has a fixed correspondence with the address of the DMA bus, the corresponding data uploaded or downloaded by the DMA bus can be found through the fixed correspondence.

[0066] In the embodiment of the present invention, the transaction describing the operation of the DMA bus can be generated by...

Abstract

The invention is suitable for the technical field of chip design and verification, and provides a verification method and a system for a converter controller. The method comprises the following steps of: acquiring data associated with affairs according to the affairs described according to DMA (direct memory access) bus operation, and generating control affairs from the affairs and the acquired data; monitoring DMA bus time sequence received or sent by the switch controller, analyzing control information in the acquired bus time sequence as control information of monitoring affairs, and reading data corresponding to the control information from prestored data associated with reading and writing of AXI (automatic X ray inspection) bus address as data information of the monitoring affairs; comparing the control affairs with the monitoring affairs, and judging whether the control information and the data information of the control affairs as well as the control information and the data information of the monitoring affairs are consistent or not. The verification environment provided by the invention is simple in the constructing process and has excellent transportability.

Description

technical field [0001] The invention belongs to the technical field of chip design verification, and in particular relates to a verification method and system for a conversion controller. Background technique [0002] In the design of a modern multimedia chip (Integrate Circuit, IC), it is often necessary to upload and download a large amount of data through different buses according to the requirements of the system or modules. This requires a converter module between buses to convert data and commands on different buses and to upload and download data smoothly. Since this converter module is usually at the system level, once a problem occurs with this module, it is likely to cause the entire chip to fail. Therefore, it is particularly important to fully verify it. [0003] Direct memory access (Direct Memory Access, DMA) bus to AXI (AdvancedeXtensible Interface) bus conversion controller, receive DMA bus slave (slave module, conversion controller is the main module of DMA...
