std_logic_vector to integer conversion vhdl - Stack Overflow

NettetTo convert an integer to std_logic_vector you have several options. Using numeric_std: vect <= std_logic_vector ( to_unsigned ( your_int, vect'length)); or vect <= std_logic_vector ( to_signed ( your_int, vect'length)); Using std_logic_arith: vect <= conv_std_logic_vector ( your_int, vect'length); NettetHardware in the loop is a widely used technique in power electronics, allowing to test and debug in real time (RT) at a low cost. In this context, field-programmable gate arrays (FPGAs) play an important role due to the high-speed requirements of RT simulations, in which area optimization is also crucial.
