The hierarchical relationship between simulation model is determined according to line type and each emulation mould is calculated based on simplex method
The level of type, simulation model are IOCE multistage-combination model.
The simulation model driving method of the present embodiment is by taking IOCE multistage-combination model as an example, and referring to fig. 2, IOCE model includes
It inputs (Input), output (Output), calculate (Calculate) and event (Event).It is i.e. defeated in certain outside or inside
Under the conditions of entering, is triggered and generated event response, calculated according to response and export result by certain message.IOCE model
Be otherwise known as atom model, may be expressed as:
Model(I,O,C,E)
Wherein, I is the condition of model, and C is the function of model, and E is the external drive for triggering C, and O is the result of model.It presses
According to data exchange relationship between model, can define:
I --- input interface, if it is inside input, then model ontology is voluntarily obtained, if provided by external model, mould
Type needs to obtain by ordering；
O --- output interface needs to issue output if external model uses the interface output data；
C --- calculate interface, processing external event excitation；
E --- external event excitation notifies, response computation for response external.
Referring to Fig. 3, multistage-combination model is called by the built-up pattern of the generation of several atom models assembling correlation function.Often
Input of the output of one atom model as another atom model.Therefore, the also not phase of the level between different atom models
Together.Line type includes wired in parallel and serial line, and the sequential relationship of the simulation model between identical layer time by connecting parallel
The mode of line is driven, and the simulation model sequential relationship between different levels is driven by way of serial line.Respectively
Input/output relation between a atom model embodies interactive relation by way of line.Hierarchical relationship is that atom model exists

Formula is parallel drive, that is, is not interfere with each other.Automobile C simulation model is 1 grade, and it is driven in series that automobile A, which drives the mode of automobile C,.
Issue broadcast drive command one by one from highest level to bottom grade.
Each level atom model needs drive one by one according to hierarchic sequence, otherwise it is possible that logic error, to lead
It causes driving cancellation to rely on and " deadlock " phenomenon occurs.Deadlock refers to two or more processes in the process of implementation, due to competing
Strive resource or as communicate with one another and caused by a kind of obstruction the phenomenon that, if they all will be unable under propulsion without external force
It goes.Claim system to be in deadlock state or system produces deadlock at this time, these forever the process waited mutually be known as deadlock into
Journey.It, can be in appearance " deadlock " phenomenon, in time by the way of publication broadcast drive command one by one in huge analogue system
Discovery there is the problem of " deadlock ", to make record and the scheduling of simulation model driver' s timing faster, solution is occurred
The problem of.
Judge whether level and the simulation model level of current broadcast drive command are identical, this layer is then driven to emulate if they are the same
Otherwise model does not drive this layer of simulation model.
After receiving broadcast drive command every time, applicability matching can be all carried out, guarantees the level of broadcast drive command driving
For this level.Prevent " deadlock " phenomenon as caused by timing confusion.
Embodiment 2:
