Runtime warnings

Recommended Posts

Hello everyone,
I've built a little system in SystemC, which compiles without errors. But when I run the simulation, I get (besides a seg fault, which I will debug) the warnings:

I've found a previous thread in the archive which discussed a similar problem:
http://workspace.accellera.org/Discussion_Forums/systemc-forum/archive/msg/msg?list_name=systemc-forum&monthdir=200506&msg=msg00014.html

Here, there were two possible solutions proposed:
-Either the warnings are because of separate multiple inheritance (class/module is inherited multiple times and so multiple objects/modules with the same sc_module_name are created) -> make class/module which is inherited virtual
-Or I have multiple objects/modules with the same sc_module_name on the same system hierarchy -> rename classes/modules

Option 1 cannot be the solution for me because the said modules are templated. And also, the only class which is inherited by all modules individually is sc_module.
Option 2 (seems) to be not working for me too, because every module I created has a unique name. Here are (all?) relevant infos on my classes/modules and constructors and how I build and connect them in sc_main:

template<unsigned int BUSWIDTH_0, unsigned int BUSWIDTH_1>
class dummy_socks: public sc_module {

     ....
}
...

                sc_time sim_time = sc_time(s_time, s_time_unit);
                // run the simulation
                sc_start(sim_time);
   ....
}

Anyone has an idea why this is happening?

Thanks and regards,
Florian

SystemC issues this warning when multiple objects were given the same name in constructor.  However, in your code I don't see an object initialized with "AT_LT_conv_pe" name, so I can't trace down the source of problem.

Hello,
I think  there must be a relation between these warnings and the fact that every said class/module has exactly the same number of amba slave sockets(these are types from the amba toolkit by Carbon Design Systems included with the header #include <amba.h>) minus one. Minus one is because the module related to the first socket doesn't have to be renamed. In my class definitions this looks like:

template<class T, unsigned int BUSWIDTH_0, unsigned int BUSWIDTH_1>
class dpr_two_even_regions: public sc_module {

   ...
           public:
                amba::amba_slave_socket<BUSWIDTH_0> slave_sock_r_0;
                amba::amba_slave_socket<BUSWIDTH_0> slave_sock_w_0;
                amba::amba_slave_socket<BUSWIDTH_1> slave_sock_r_1;
                amba::amba_slave_socket<BUSWIDTH_1> slave_sock_w_1;
};
...
template<class T, unsigned int BUSWIDTH_0, unsigned int BUSWIDTH_1>
class dpr: public sc_module {

   ....
           public:
                amba::amba_slave_socket<BUSWIDTH_0> slave_sock_r_0;
                amba::amba_slave_socket<BUSWIDTH_0> slave_sock_w_0;
                amba::amba_slave_socket<BUSWIDTH_1> slave_sock_r_1;
                amba::amba_slave_socket<BUSWIDTH_1> slave_sock_w_1;
};
...
template<unsigned int BUSWIDTH_0, unsigned int BUSWIDTH_1>
class dummy_socks: public sc_module {

        public:
                amba::amba_slave_socket<BUSWIDTH_0> slave_sock_dummy_1;
                amba::amba_slave_socket<BUSWIDTH_0> slave_sock_dummy_2;
                amba::amba_slave_socket<BUSWIDTH_0> slave_sock_dummy_3;
                amba::amba_slave_socket<BUSWIDTH_0> slave_sock_dummy_4;
                amba::amba_slave_socket<BUSWIDTH_1> slave_sock_dummy_5;
                amba::amba_slave_socket<BUSWIDTH_1> slave_sock_dummy_6;
                amba::amba_slave_socket<BUSWIDTH_1> slave_sock_dummy_7;
                amba::amba_slave_socket<BUSWIDTH_1> slave_sock_dummy_8;
   ...
};

Does this mean each socket calls the sc_module constructor with the same sc_module_name?
Greetings Florian
