digital logic - How does VHDL handle bitwise operations?

Witryna11 wrz 2024 · In general it is very helpful to think about the intended meaning of all these values. In VHDL std_logic there are 9 distinct logic values which we can roughly group as follows: Four of these values, '1', '0', 'H', and 'L' represent known logic levels with various drive strengths. Another four of these values, 'X', 'U', 'W', and 'Z', all ... Witryna12 kwi 2024 · VHDL doesn't expose the underlying implementation for type integer which is defined by a range of values and a set of operations.
