Re: Signal 'ramp implicit quantity

Amro,

If sbit is a signal of type bit, the notation sbit'ramp is erroneous. So 
it is for any signal of a non floating-point type or subtype. One reason 
for that is it would be fairly complicated or clumsy to define common 
underlying standard semantics to convert a logic type value into a 
proper real value.

Best regards,
Alain
