Witryna21 sie 2024 · Aug 21, 2024 at 16:35. I'm going to guess VHDL is always "bitwise" and never "logical" unless you convert the type to a scalar type: std_logic, bit, or boolean. Mostly, because VHDL is based on ADA language, a strongly typed language, and verilog is based on the c-language a weakly typed language that needs to make a … 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 ...
