I am fairly new to digital logic designing and I need some help in regards to finding a BCD to 7 segment decoder on software. I am using proteus for my counter, and for some reason I am unable to make it work. It either gives low and grey outputs only, no high output for my display. Any help would be appreciated.
That won't be very useful if the LED's cannot be driven from an LCD display and must be the correct polarity to match if low side segments or high (common cathode).
These designs are obsolete anyways and you can choose a better example to learn.
I'll post a link to an old discrete version of Binary to BCD decoder in comment. You can toggle the 1/0 and see the display change.
