2 things here:
- firstly binary ops really need not 4G ops to test them all, but 4G2 ops which is not a 'few seconds' but 4G times a few seconds
- secondly, as a chip designer, by the time you've got silicon it's essentially too late - testing 4G or 4G2 operations in the original verilog/vhdl model is very much not a few seconds or 4G times a few seconds
