Technical field
The present invention relates to communication technical field, specifically, relate to a kind of checking case generation method and device.
Background technology
Checking is the process that is used for proving that the function of design is whether correct, and checking case and verification environment are two key elements of chip checking.The checking case of existing baseband chip generally adopts PERL (PracticalExtraction and Report Language, the practical extracts and schedule language) to realize.Checking case generally comprises configuration file and data streaming file.Wherein, configuration file is to the different register configuration parameter of circuit input, to reach the detection under the circuit different conditions; Data streaming file is to the different data block of circuit input.
And the reference model of checking is that the behavioral scaling of circuit function is described with the function and the algorithm of high-level language realization circuit.Reference model is corresponding to up coding module algorithm link, and its function at first is verified in the software algorithm checking, and in Circuit verification, whether correct reference model as testing circuit function a standard.The uplink downlink reference model made in the general C language that adopts, and realizes the performance evaluation to each channel.When checking, call the executable program of reference model by the PERL script, obtain the input and output data of normative reference model, and will import data as DUT (Design Under Test, tested design) excited data disposes frame sequence and the frame sequence parameter consistent with reference model, obtains the data of DUT, then the data of DUT are compared with the standard dateout, be verified the use-case execution result.
Yet, the inventor finds in realizing process of the present invention, the input and output data of the normative reference model of prior art are to obtain from single business reference model, for the checking case that needs the multiframe combination as speech business, prior art can't produce the normal data after the up coding of baseband chip, in order to checking.
Summary of the invention
Embodiment of the invention technical problem to be solved is to provide a kind of generation method and device of checking case, solves the defective that prior art can't be verified the multiframe combination services.
The embodiment of the invention is achieved in that

Embodiment
Further specify the technical scheme of the embodiment of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, the embodiment of the invention one provides a kind of checking case generation method, comprising:
Each single operation code normal data in step S101, generation CS territory (Circuit Switched domain, circuit domain).
Step S102, single operation code normal data is carried out script splicing, obtain complete data block.Described script splicing can adopt the script opsition dependent to splice.
Step S103, described data block is generated burst (burst).
Step S104, described burst is modulated, generate modulating data.
The embodiment of the invention two also provides a kind of checking case generation method, as shown in Figure 2, comprising:
Interleaved encoded data 116bits in each single professional piece in step S201, the generation CS territory.
Insufficient in order further to solve the checking that available technology adopting customization mode delta frame sequence causes, in this step, can adopt the mode of random schedule to generate interleaved encoded data in the piece, interleaved encoded data is a frame sequence in this piece, and the frame genesis sequence adopts random schedule in possible combination.
Step S202, employing script carry out interblock with interleaved encoded data in single business module of different business and interweave, and form complete 116bits data block.
Step S203, for the 116bits data block after interweaving is carried out a better protection, can encrypt described data block.Coded data after interblock interweaved corresponding frame number and 64 bit encryptions at random continuously obtain the encryption random bit of 114bits, carry out computations with described interleaved encoded data then, draw the enciphered data of final 114bits.The control channel indicating bit here (generally be the 57th and 58bit) is generally can not be encrypted.
Step S204, the 116bits data block after will encrypting add tail bit, training sequence bit and protection bit at interval, generate burst.
Generating preceding 4 burst as speech frame effectively fills for the idol position, 4 burst in back are that effectively fill strange position, except at the beginning 4 burst effectively fill entirely, several burst of back are that interblock interweaves, also can form a full frame together because run into the SID control frame with former frame, the SID_FIRST frame that for example indicates the voice end is made up of four burst, the coded data part of its each burst only in the idol position effectively, back 4 burst with last speech frame only fill odd bits like this, just gather into a full frame, generate burst then together.
Step S205, burst is modulated according to separately type selecting modulation system, generate modulating data.The modulating data that generates is used for comparing with DUT.
As shown in Figure 3, the embodiment of the invention three provides a kind of checking case generating apparatus, comprising:
Normal data generation module 31 is used to generate each single operation code normal data in CS territory.
Wherein, described normal data generation module 31 can be used to adopt the mode delta frame sequence of random schedule for normal data generates submodule, to generate single operation code normal data in CS territory.
Described script concatenation module 32 can be the interblock interleaving block, is used to adopt script that interleaved encoded data in single business module of different business is carried out interblock and interweaves, and forms complete data block.
Described checking case generating apparatus can also comprise encrypting module 35, is used for described data block is encrypted, and the data encrypted piece is sent to the burst generation module.
Described burst generation module 33 can be used for the data encrypted piece is added tail bit, training sequence bit and protection bit at interval for burst generates submodule, generates burst.
Described modulation module 34 can be the modulation submodule, is used for burst is modulated according to type selecting modulation system separately, generates modulating data.The modulating data that generates is used for comparing with DUT.
