Embodiment 1

[0034] see figure 2 , an Address object contains the following key-Value:

[0035] city: ShangHai street: YiJiang Road postcode: 202014

[0036] Expressed in json as follows:

[0037] {"city": "ShangHai", "street": "YiJiang Road", "postcode": 202014}

[0038] Among them, Value can also be another Object or an array, so complex Objects can be nested,

Embodiment 2

[0040] see image 3 , a Person object contains name and address, which can be expressed as follows:

[0041] {"name":"Samson", "address":

[0042] {"city": "ShangHai", "street": "YiJiang Road", "postcode": 202014}}

[0043] By creatively using the json format as the data exchange between the test case and the verification environment, the restrictions on the programming language and platform of the test case writing are liberated, the efficiency of the test case writing is improved, and the data structure can be serialized through the existing json library And deserialization, it is easy to track the sending and feedback of test data packets.

[0044]It can be seen from the above that the present invention not only has high programming efficiency, but also facilitates test case management, rollback testing, and error tracking.

Abstract

The invention discloses a method for checking a cross-platform and cross-language single-chip system. The method comprises the following steps of: constructing a checking module by using a system c, namely realizing a server thread to monitor an appointed port, establishing a transmission control protocol/Internet protocol (tcp/ip) link service, resolving a data stream of the port through a loop body, obtaining a data structure sent by a client by using a standard json resolving function, making a corresponding response according to branch judging, constructing a returned json data packet, and repeating the steps until the link is interrupted to quit the simulation, wherein a programming language can be freely selected from the client to compile a test case, i.e., the operation to the checking module is packed by a json base of a corresponding language and sent through the tcp/ip link so as to control the flow of the tested checking module. The method is higher in programming efficiency and is favorable for management and rolled-back test of the test case and error tracking.

Description

technical field [0001] The invention relates to a verification method for a single-chip system, in particular to a verification method for a cross-platform and cross-language single-chip system, and is particularly suitable for data exchange in the json format. Background technique [0002] The verification methods of the functional modules of the current single-chip system mainly include the following modes: RTL module code + behavior-level description code; RTL module code + special verification language behavior-level description code; RTL module code + PLI calling C function. [0003] However, the above modes are generally only widely used in verification methods in the field of application-specific integrated circuits (ASICs), while in the field of single-chip systems (SOCs), there are the following disadvantages: [0004] First of all, the functional modules of a single-chip system are generally driven by software, and the complexity of the driver increases greatly wit...
