The simulation program is running very slowly. It displays a 1 Hz sine voltage with a 60 ms scanning frequency in 12 steps. Next to the S-R flip flops is the source of the scanning frequency and the sine signal. Actually, my intention was to combine the 2 signals and see them on the screen, but I couldn't fit them. If I had produced and provided the signal sources myself, it could have worked faster, but there was no space left, I could barely fit them. I could have made the 12x12 LEDs smaller and provided a little more space, but the phone overheated.
