When you choose a target configuration, you implicitly choose a code format. If you use Real-Time Workshop Embedded Coder, for example, the code generated will be in embedded C format. The embedded C code format is a compact format designed for production code generation. Its small code size, use of static memory, and simple call structure make it optimal for embedded applications.
Many other targets, such as the generic real-time (GRT) target, use the real-time code format. This format, less compact but more flexible, is optimal for rapid prototyping applications.

thx Walter...
in crisp...
simply the grt target for PC level simulation. Not intended for flashing into a HW.
But ert is target intended. used for an optimized code generation in production. Different HW suppliers will supply their own target files.. example.. If we purchase TI 28XX DSP boards, with Simulink libraries they supply their own target files..
thx,
