Getting a bit from bus in SystemC Language Posted February 15, 2018 · Report reply Hey. It's my first time with SystemC and I'm having the following problem: I made a control matrix that generates a 12 bits control word (sc_bv<12> CON) and I'm trying to get the 10th bit of that word. On my top level cpp I did the following: sc_signal<sc_bit<12> > bus_CON; sc_bv<12> var_bus_CON; var_bus_CON = bus_CON; sc_signal<bool> busCON10; busCON10 = var_bus_CON; and after I'm connecting the ref. variable that I want with that previous signal: programcounter.Ep( busCON10 ); And It's not working. My signal gives me hi impedance at all simulation time. A case that should happen when Ep = 0. p.s: matrix.CON( bus_CON ); Did I make anything wrong?
