Writing Target Language Files

3-38

By including this simple target file for this S-function block, the code is

generated as:

void

MdlStart(){}

void

MdlOutputs(tid)

{

/* S-Function block: foo */

rtB.foo = rtGROUND * rtP.foo.gain;

}

void

MdlUpdate(tid){}

void

MdlTerminate(){}

/* function to register model in SimStruct */

Simstruct *foogain()

{

: /* Model Registration

(does NOT need to register S-function) */

}

So, including a TLC file drastically decreased the code size and increased the

execution efficiency of the generated code. These notes highlight some

information about the TLC code and the generated output:

Note 1

The TLC directive %implements is required by all block target files, and

must be the first executable statement in the block target file. This

directive guarantees that the Target Language Compiler does not

execute an inappropriate target file for S-function

foogain.
