I am implementing a Linear Feedback Shift Register (LFSR) in Pspice A/D with a new logic family. Anyways, to initiate the random number generation I am required to feed in some value to the circuit, to be specific, the output of all the D-latches can not be zero initially so I am trying to make the output of any D-latch '1' initially. It should be done such that after the initialization the circuit works by itself. I tried using a fixed voltage source but that does not work, quite obviously. Please suggest anything you may find applicable to this.
Below is the circuit I am trying to make:
And just in case it may help, I am trying to get results like these:
