Parameters

system

-

`module` ; Msim model

options

-

(optional) equation(s) of the form name = value

Returns

• 

none

Options

• 

target : one of the following: "EMI", "SIT"

  

Specifies the target platform for which the code will be generated. Default is "EMI".

• 

name : string

  

Specifies the filename of the generated C file. Default is "MsimModel".

• 

outputdir : string

  

Specifies the output directory for generated files. Default is "kernelopts('homedir')".

• 

pathEnvironment : string

  

Specifies the path to the EMI or SIT installation directory. Default is "C:/Program Files (x86)/National Instruments/LabVIEW 2012".

• 

pathVC : string

  

Specifies the path to the Visual C++ installation directory. Default is "C:/Program Files (x86)/Microsoft Visual Studio 10.0/VC".

• 

initial : set of equations

  

Specifies the initial conditions for all system's states, ix1 variables, and inputs.

• 

inputs : list of functions

  

Specifies system's input variables.

• 

outputs : list of functions

  

Specifies system's output variables.

• 

params : list of equations

  

Specifies values of system's parameters.

• 

nosubs : true or false

  

Specifies whether the parameters are entered as the original model names or the substituted names.  Default is false.

• 

optimize : one of the following: false, "subexpronly", "fast", true

  

Specifies level of code optimization (false = None, true = Full).  Default is "subexpronly".

• 

coniter : non negative integer

  

Specifies constraint iteration count.  Default is 20.

• 

contol : positive

  

Specifies constraint tolerance.  Default is 1e-7.

• 

evtiter : positive integer

  

Specifies maximum number of event iterations.  Default is 10.

• 

evtproj : true or false

  

Specifies use projection in events.  Default is true.

• 

evthyst : non negative

  

Specifies width of event hysteresis band.  Default is 1e-10.

• 

fixedstep : true or false

  

Specifies whether to optimize for use with fixed-step integrators.  Default is false. fixedstep must be true when target = "SIT".

• 

diagnosticinfo = true or false

  

This option only suported when target option is set to "EMI". This option specifies whether to provide run-time diagnostics in the generated EMI block.

– 

When specified as true, engine will add two outputs to the bottom of the EMI block, EventIterations(t) and ConstraintIterations(t), in that order.

– 

Note that if the EMI inputs/outputs are grouped into vectors, these outputs will be placed in the group DiagnosticInfo.

– 

This option will be available for both, EMI fixed-step integrators, and for EMI variable-step integrators, and in the latter case, will report on the maximum of the value obtained since the last output point.

  

Default is false.

• 

discretize = true or false

  

Specifies whether to export as a discrete model (no continuous states).  Default is false.

• 

solver = one of the following: "Euler", "RK2", "RK3", "RK4", "ImplicitEuler"

  

If target option above is set to "EMI" and discretize option above is set to true, specifies which external solver to be included in the exported discrete model. Default is "Euler".

• 

timestep = non negative

  

If target option above is set to "EMI" and discretize option above is set to true, specifies the exported model's discrete timestep. Default is 1e-3.

• 

inpnumdiff : true or false

  

Specifies whether to use numeric derivatives for inputs.  Default is false.

• 

addoutputs : one of the following: "none", "states", "statevals", "continuous", "all"

  

Specifies which additional variables need to be included in outputs.  Default is "none".

• 

optionsSIT : list: [nonnegative, {"internal", "external", "internal&external"}]

  

Specifies [baserate, inputTypes].  baserate is the rate at which the model will run. inputTypes specifies type of inputs: internal, external or both. Default is [0.001,"internal&external"].  When target is set to "EMI", optionsSIT option is ignored.

Description

• 

The GenerateCode command generates LabVIEW EMI or NI VeriStand and LabVIEW SIT component code from a MapleSim system.
