accessing port data types during Complilation

Hi,

I am masking addition block, i need to access the port datatypes of the Addition block.

I have written the code in initialization tab of the mask system, to access the port datatypes i used the below code

IportBlks = find_system(mdlName, 'LookUnderMasks', 'on','BlockType', 'Inport')
InportDTs = cell(numel(IportBlks))
modelname([],[],[],'compile')
for i = 1:numel(IportBlks)
  IportBlk = IportBlks{i}
  q=get_param(IportBlk,'PortHandles')
  InportDTs{i} = get_param(q.Outport,'CompiledPortDataType')
end
modelname([],[],[],'term');

Its not working, but if i run the same code on Command window it will work.

let me know do i need to change the code or any alternative way is there.

You cannot run this code during mask initialization, because mask initialization is actually one of the stages of the model compilation process (the command "modelname([],[],[],'compile')"). Is there a reason you want to get the CompiledPortDataTypes for all Inport blocks in your model? Perhaps there is a better solution.

My main question is whether my mask code can appear in C Code when we generate the code by using E-coder.

for your question:

I am creating generic libraries for my application. my libs need to access the data types when the model is running.

for EG: if i am masking Addition block, suppose i am getting Uint16 and int16 as my port data types, my mask block should replace the code with add_U16_S16(). its a function call for my application.

Mask initialization code is not generated into the code generated by Simulink/Embedded Coder.

I would recommend post-processing the generated code using the after_tlc in STF_make_rtw_hook.m - you need to create a custom target that inherits from ert.tlc for this.
