How to convert custom simulink blocks (with inports and outports created for accessing hardware interfaces) inside a subsystem into non-virtual blocks?

I'm working on a project which has custom simulink blocks (with inports and outports created for accessing hardware interfaces) within subsystem. But embedded coder didn't generate code for it stating its a virtual block. So how to convert these virtual blocks (Inports and Outports) inside a subsystem into non-virtual blocks? Or is there any other way so that embedded coder will generate code for it.

Select the Subsystem block, right click, select "Block Parameters (Subsystem)", check "Treat as atomic unit".

This is one of the ways to change between virtual and non-virtual.

Conversion of subsystem into atomic subsystem may affect the overall execution of logic. Is there any alternate way to generate code for virtual blocks (Inports & Outports)?

I think what you are really looking for is to generate code according to a specific interface. Start from here you might find what you want.

I forgot to mention one important point that these inports and outports are of the custom simulink blocks which are created for accessing hardware interfaces. I have modified the question and description accordingly. Please help!

Hi..Attached is the one of the Custom Block library file and as suggested below is the snap of the same block where "Treat as atomic unit" is alredy checked. But still issue is there.

[Fangjun Jiang]

This block is an empty Subsystem block. There are no Port blocks inside. The port icon and label are from the "mask" of the Subsystem block. Select the block, right click, select Mask, Edit Mask, look at the Icon panel.

Thare are nothing there.

There are some codes related to the mask initialization but nothing indicates anything related to the embedded code generation.
