Warning: SystemC-AMS: Write not called for decoupling outport

[A.Elgogary]

i keep receiving the error (just on time) for TDF Output port with 10ms time step and 5 rate and sca_tdf_out_dt_cut, connected to 2ms TDF model??

Could you please check with SystemC AMS 2.1 PoC and report if the warning is still there?

It would be helpful if you could post a minimal self-contained example demonstrating your issue.

[A.Elgogary]

Here is an Example which give the same warning :

#include "systemc.h"
#include "systemc-ams.h"

SCA_TDF_MODULE( ModuleIn ) {

	sca_tdf::sca_in<double> q;
	sca_tdf::sca_out<double> q2ms;

	void initialize() {

	}
	void set_attributes() {

		set_timestep(2, SC_MS);
	}

	void processing() {
		q2ms = 0;
		cout << q << endl;
	}

	SCA_CTOR( ModuleIn )

	{
	}

};

SCA_TDF_MODULE( ModuleOut ) {

	sca_tdf::sca_out<double, sca_tdf::SCA_DT_CUT> q;
	sca_tdf::sca_in<double> q2ms;

	void initialize() {
		//q.set_rate(5);
	}
	void set_attributes() {
		q2ms.set_rate(5);

		set_timestep(10, SC_MS);
	}

	void processing() {
		q = 1;
	}

	SCA_CTOR( ModuleOut )

	{
	}

};

SC_MODULE( MainModule ) {

	ModuleOut * ModuleOut0;
	ModuleIn * ModuleIn0;

	sca_tdf::sca_signal<double> q, q2ms;

	SC_CTOR( MainModule ) {

		ModuleOut0 = new ModuleOut("ModuleOut0");
		ModuleOut0->q(q);
		ModuleOut0->q2ms(q2ms);

		ModuleIn0 = new ModuleIn("ModuleIn0");
		ModuleIn0->q(q);
		ModuleIn0->q2ms(q2ms);

	}

	~MainModule() {

	}

};

MainModule * MainModule0 = NULL;

int sc_main(int argc, char* argv[]) {

	MainModule0 = new MainModule("MainModule0");

	sc_start(100, SC_MS);

	return 0;
}
