VHDL Rising Edge Detection

If you are writing a VHDL submodule and want to detect the rising edge of a specific signal, you may think that “rising_edge(my_signal)” or “my_signal’event and my_signal = ‘1’” logics come through this issue. Nevertheless, this function works only for external clock signals. If you make a definition in the code like “rising_edge(my_signal)” or “(my_signal’event and my_signal = ‘1’)”, your HDL code will not work as you wanted. Therefore, to find the rising edge, it would be better to start with the following VHDL code. VHDL Module Design Testbench Simulation… Daha fazlasını oku »VHDL Rising Edge Detection
