Ibrahim,

sc_in is a template class. The | operation is to perform on the template
parameter. Template parameters can be standard types(int, sc_bit, char,
etc....) or used defined types. Since implementation of the operator varies
across the types sc_in does not define this.


You need to modify your code to:
c->write(a->read()|b->read());
It is safe to use read and write defined for sc_in and sc_out respectively
to perform this operation.

BR,
Rohit
