Writing a Block Target File
3-17
As an example, given S-function foo requiring a #define and two function
declarations in the header file, you could define the following function.
%function BlockTypeSetup(block, system) void
%% Place a #define in the model's header file
%openfile buffer
#define A2D_CHANNEL 0
%closefile buffer
%<LibCacheDefine(buffer)>
%% Place function prototypes in the model's header file
%openfile buffer
void start_a2d(void);
void reset_a2d(void);
%closefile buffer
%<LibCacheFunctionPrototype(buffer)>
%endfunction
TLC Output Block Functions
The remaining block functions are Target Language Compiler output functions
executed by the system target file
mdlbody.tlc for each block in the model.
Enable(block, system)
Nonvirtual subsystem Enable functions are created whenever a Simulink
subsystem contains an Enable block. Including the
Enable function in a block’s
TLC file places the block’s specific enable code into this subsystem
Enable
function. See
sin_wave.tlc for an example of the Enable function.
Disable(block, system)
Nonvirtual subsystem Disable functions are created whenever a Simulink
subsystem contains a Disable block. Including the
Disable function in a block’s
TLC file places the block’s specific disable code into this subsystem
Disable
function. See
outport.tlc for an example of the Disable function.
