Hi
I am using 2 BCD counters (4510) and 2 BCD to 7segment decoders (4511) to allow countdown from 16 to 00. I need some help finding a way to preload the BCD counters when the output of both counters are 0000 0000 to 0001 and 0110. I have tried the simulation in Multisim using an 8-input NAND and an inverter connected to the preload pin but somehow it doesn't work.
Thanks
