In the HES-DVM generated SystemC wrapper, there are some interface signals which are not in the list of I/O signals of DUT, what is the purpose of these signals?

sc_core::sc_signal<bool> p0; sc_core::sc_signal<bool> p1; . . sc_core::sc_signal<bool> p63;

ANSWER

Signals p0, p1,...p63 come from HES mapping file. This is how we reference each bit of DUT interface in hardware. Concatenation to real signals is done in SystemC or VHDL/Verilog wrapper.
