Hi,
I have a doubt for the FF startup value hope can get the answer through this forum.
Let said we build a positive clock edge Flip-flop with preset and clear control on our die.
If the preset and clear signal not being active at the startup and the clock signal maintain as low,
what would be the output of the FF? Would it be some value either '1' or '0' or it would be undefined ('X')?
Someone told me that due to the die characteristic, the FF will have some initial value even it not being preset and clear at the startup with the clock never toggle before. Is it true?
Thanks.
