Witryna22 sie 2024 · The most common type used in VHDL is the std_logic. Think of this type as a single bit, the digital information carried by a single physical wire. The std_logic gives us a more fine-grained control over the resources in our design than the integer type, which we have been using in the previous tutorials. Normally, we want a wire in a … WitrynaTo declare a signed variable, use signed keyword such as logic signed [15:0] a.
