    Hi,
    I want to make an N-width shift register, with N flipfliops in the
    schematic composer. Is it possible to use a parameter N for the number
    of flipflops? I tried I1<1:N> on the flipflop instance and s<0:N-1> and
    s<1:N> on the D input and Q output respectively. But this doens't work.
    Does anybody know if there is a way to do this?

    Kind regards, Wim de Haan

    This can be done using a schematic pcell - where the width is a parameter.

    An example of doing something like this can be found at:
