For the MATLAB Function block, you can use the InstantiateFunctions parameter
to generate a VHDL® entity or Verilog® module for
each function. HDL Coder™ generates code for each entity or module in
a separate file.
The InstantiateFunctions options for the MATLAB Function block are listed in the following table.
| InstantiateFunctions Setting | Description |
|---|---|
'off' (default) | Generate code for functions inline. |
'on' | Generate a VHDL |
To set the InstantiateFunctions parameter using the HDL Block Properties dialog box:
Right-click the MATLAB Function block.
Select HDL Code > HDL Block Properties.
For InstantiateFunctions, select on.
To set the InstantiateFunctions parameter
from the command line, use hdlset_param. For
example, to generate instantiable code for functions in a MATLAB
Function block, myMatlabFcn, in your DUT
subsystem, myDUT, enter:
hdlset_param('my_DUT/my_MATLABFcnBlk', 'InstantiateFunctions', 'on')If you want to generate instantiable code for some functions
but not others, enable the option to generate instantiable code for
functions, and use coder.inline. See coder.inline for details.
The software generates code inline when:
Function calls are within conditional code or for loops.
Any function is called
with a nonconstant struct input.
The function has state, such as a persistent variable, and is called multiple times.
There is an enumeration anywhere in the design function.
