Does anyone have any ideas how to make this assignment in a single line?


sc_signal<256> my_signal;

sc_biguint<128> my_variable;

my_variable = my_signal.read().range(191,64):


If I try to compile that using Visual Studio (I have SystemC 2.2) I get:

1>.........cpp(57) : error C2593: 'operator =' is ambiguous
1>

1>        [
1>            X=sc_dt::sc_bv_base
1>        ]


I also looked at the .to_xyz() conversion methods but there's nothing 
that supports values > 64 bits.   I guess I could make several slices 
however that will be awkward if the range values are variables.

Has anyone any ideas for simple ways to do this?

Thanks,
