is it possible to execute two different threads of same systemC module parallelly. like can we store resultant output of one thread in file mean while another thread output at console, all at same time?(in sense of real time).

signal is used to connect two input and output ports of two different modules and vctr is a structure consist vector as a field as i can't use vector directly as a data type here. in my code i am getting the output what i want and then getting the above mentioned segmentation fault. any idea?

here, sc_signal is used to connect input and output ports of two different modules and to transmit a vector through this. as can't use vector as data type directly so created a structure consist vector and used as a pointer here. SC_MODULE(ETSystem) { sc_signal<vctr*> B_in; // ... SC_CTOR(ETSystem) :reg("reg") , buffer("Buffer") , emac("EMAC") , ephy("EPHY") ,memory("memory"){ // Connect modules initiator = new Initiator("initiator"); initiator->socket.bind(memory.socket); initiator->tx_irq.bind(memory.tx_irq); memory.tx_irpt(flag); reg.tx_enable(flag); memory.output(B_in); buffer.input(B_in); // ... } }

here i am facing memory deallocation issue while using sc_signal<vctr*> B_in; where vctr is a structure consist vector as a field.
