Hello all
I am trying to use the shift register within vsm. I have used one model but it did not have a pin for the shifted out bits. I am now using the shiftreg_4 primitive. What I am trying to find is the pin explanation for this model. What is DL, DU, QU, and QL? I want to use it as a serial in, parallel out register. I do not understand which one is the input pin for data, i assume it is one of the pins starting with D. And which one of the pins are the parallel out pins, i assume it is the pins labeled Q0-Q3. I am also guessing the reset pin should be grounded, the OE pin to 5 volts. What does up and hold mean on the primitive. Help is appreciated thanks.
