3rd edition.

I make use of the smallest simulation step of EC and the output is okay in my smartphone. But the output runnung too fast in chrome browser, and it does not demonstrate the actual behaviour of the real circuit.

I have a great desire to learn and understand hardware from its roots and this is amazing.

Amazing job! Never seen the whole board used like that. Very nice!

It took me a while to find out what you have changed. Nice trick, but this is not the original idea. Anyway, its working much smoother and probably it doesn't matter how you finally made it quicker. To overcome the convergence problem one way is to drive LED at there nominal voltage without current limiting resistor. In this case it would be 5V 7segment leds with 1mOhm resistor in front. Keep it up!!!

Yes, if I set the led to 3V, my smartphone will not be frozen, and responds at reasonable speed. But the leds are dim and uneven. It seems the brightness is related to the driving time.

I just observed this demo is running too fast on chrome browser for pc. And it is difficult to set the update time for best result. It seems my original demo using timer source is the best.

LED voltage 4.9V and 1mOhm resistance and simspeed 1s/s works great.
