hdl code generation from simulink model

Hello, I am trying to generate VHDL code for my simulink project. I am using matlab 2020 and my model has two adress entries, which are connected to a FROM File that read adress data from a '.mat' file.

I get this final error as shown in the figure. during the code generation I commented the two input From File, which was demanded by the 'HDL Code Generation Check Report' as error correction.

So the two inputs of the model still with no data, I don't know if this is the cause of the error.

Thank you so much for your help and time.

All input ports are connected to DUT shold be connected with valid sample times.

Run "hdlsetup" command and make sure all sample times are defined. No pink (inf sample time color) inside the DUT. If there are constants associate sample time or add -1 as sample time to inherit sample times for back propagation.

Run this check to make sure you do not have invalid sample times in the DUT

Check for infinite and continuous sample time sources

Thank you so much Mr Kiran.

I have already runned the "hdlsetup", and yes indeed I have the two entries signals in pink. How can I associate sample time or add -1 as sample time (Is it the setting of block or hdl generation settings). I tried to change the sample time of "From File" to (-1), I tried also the "Check source blocks with infinite or continuous sample time", and I clicked "modify settings", and I get the "Check for infinite and continuous sample time sources" passed. But I still have the same error and the same pink color.

Hello again Mr Kiran Sorry for disturbing you, I want to get you the complete idea. When I commant the two "From File" block I get the pnk color, but When I uncoment them the signals sample time looks perfect (no pink), but I get another error, which says I should commant the "From File" blocks to correct the error.

Thank you sir, and everyone can help me.
