Dynamic communication path in SystemC/TLM

[Tedy]

Hi,

 

To create a dynamic process we have to use sc_spawn function, I want to know if it is possible to create a dynamic port ? else, how we can create a dynamic communication path between two components ?

 

Thanks

Ted

There's not a dynamic port. The structure (modules/ports/channels) of a SystemC model is static once elaboration is complete.

 

TLM is intended to model systems using memory-mapped busses. In that case you could use a router, and re-program the routing during simulation - but there's no direct built-in support for that, you'd have to make or buy a router model,

 

kind regards

You can do this with pointer to port or using sc_vector;

 

for example:

SC_MODULE (test_mod) {

sc_in<unsigned>  *data_port;

...
SC_CTOR(test_mod) {
if (create_data_port)
    data_port = new sc_in<unsigned> ("port_name");

}


}

Thank you,

 

I mean by dynamic communication path, the connection and dispatch of ports and channels after simulation has started.

So, except the sc_spawn for a dynamic thread, is there any other dynamic structure to implement such dynamic ports ? otherwise is it possible to do this with a dynamic thread (to connect/dispatch ports and channels after the elaboration step) ?

No, it's not possible to create or connect ports after elaboration.
