Ok. I decide to try Actin HDL (student edition). I made basic code. How can I test it? I can't find good tutorial on google.
Once you have written your code, you have to compile it (Design -> Compile).
If you don't have any errors, then you can simulate. First you have to initialize the simulation (Simulation -> Initialize simulation). If it is your first time you initialize that project, a windows will pop up asking you to select the code you want to simulate.
Then, all your I/O, signals, variables, constants, etc. will appear on the lower left hand side of the screen.
After that, you should click on the icon next to the save button to open the waveforms window, where you will see your signals. Then add the signals you want to see by dragging and dropping them to the waveform window.
Then you should add some stimulators to the inputs. You do that by right clicking the the signal and selecting "Add stimulators". There you can add a clock signal, a constant value and many other things depending on the circuit and on what you want to see. If its a combinational circuit, I recommend to add clock signals with frequencies that are multiples of each other.
Finally, enter the time of the simulation and click on "Run for" (F5).
Have fun!
