Abstract
Integrated circuits having groups of flip-flops with the option to ignore control signals are disclosed. For example, an integrated circuit comprises a first group and a second group of flip-flops that share a common reset signal, and a first selection unit for selecting a first output from among the common reset signal and a logical low signal to be sent to the second group of flop-flops. A selection of the logical low signal is for preventing the common reset signal from being applied to the flip-flops in the second group. The integrated circuit may also include a second selection unit for selecting a second output from among the common reset signal and a logical low signal to be sent to the first group of flop-flops. A selection of the logical low signal is for preventing the common reset signal from being applied to the flip-flops in the first group.
