I'm not sure what to do, really ^^'
I'm not familiar with sc_buffer nor default_event().
I have this code right now. But in this way I can't react to two ones (1) coming in serie, because there has been no change on the input.
Testbench:
int sc_main(int argc, char **argv)
{
sc_time sim_time(atof(argv[1]), SC_SEC);
char *infile = argv[2];
sc_signal<bool> sig;
// create modules
Generator generator("Generator", infile);
Controller controller("Controller");
// connect channels to ports
generator(sig);
controller(sig);
}
(stimuli) Generator:
SC_MODULE(Generator) {
sc_out<bool> sensor;
[...]
}
Generator::Generator(sc_module_name name, char *datafile)
: sc_module(name)
{
in = new ifstream(datafile); // open input file (it is a file of ones and zeroes, a 1 indicating the sensor getting a new registration)
SC_THREAD(generate_thread);
}
void Generator::generate_thread()
{
for (;
{
bool sens;
wait(1,SC_SEC); // generate new inputs every second
*in >> sens; // read from file
sensor = sens;
}
}
(DUT) Controller:
SC_MODULE(Controller) {
// input ports
sc_in<bool> sensor;
[...]
//internal variables
int value;
//method
void increase();
// thread
void controller();
SC_CTOR(Lights)
: value(0)
{
SC_THREAD(controller);
sensitive << sensor;
SC_METHOD(increase);
sensitive << sensor;
dont_initialize();
}
}
void Controller::controller() {
while(true) {
while(value == 0)
wait(); //this could/should wait for an event trigger fired by increase() instead.
if(value > 0)
{
value = 0;
wait(20, SC_SEC);
}
Some_Other_Stuff();
}
}
void Controller::increase(){
//if(sensor == 1)
++value;
}
As you see, instead of this signal I would like to trigger the method increase from another module. But I am not sure how to do this. I could let Generator send pulses. But it doesn't feel right.
All help is muchly appreciated.
