Web26. nov 2024. · 7. My advice is: don't use ieee.std_logic_arith. It's proprietary (not officially part of VHDL) and causes far, far more problems than it solves. Use only numeric_std and you can do everything you need: to_integer (unsigned (X)) and to_integer (signed (X)), where X is an std_logic_vector. To convert back in the other direction: Webstd_logic_arith. This is the library that defines some types and basic arithmetic operations for representing integers in standard ways.

WebThe std_logic_arith comparison functions are similar to the built-in VHDL comparison functions. The only difference is that the std_logic_arith functions accommodate signed numbers and varying bit widths. The predefined VHDL comparison functions perform bit-wise comparisons and so do not have the correct semantics for comparing numeric values.
