Using a module inside another SC_MODULE

[foobar42]

Hi,

I'm new to SystemC and fail to use a SC_MODULE in another SC_MODULE.

My code looks somewhat like this:

SC_MODULE(module0) {

...

};

SC_MODULE(module1) {

module0 mod0("mod0");

...

};

When I want g++ to compile this, it bails out with the following error message:

sd_adder.h:19: error: expected identifier before string constant

sd_adder.h:19: error: expected ‘,’ or ‘...’ before string constant

Is it somehow possible to use modules in other modules?

You need to instantiate the sub-module as a member in the parent module. Modules are just regular C++ classes, same rules apply.

SC_MODULE(module1) {

 SC_CTOR(module1)
   : mod0( "mod0" ) // initialise member in constructor
 {
   // ...
 }

private:
 // sub-module member declaration
 module0 mod0;
};

Hi Philipp,

that did the trick for me. Thank you!
