[myhdl-list] Synchronous Set

[Colin B. <col...@gm...>]

Hello,

I'm wondering what the best way of doing a synchronous set in MyHDL is.
Since there doesn't seem to be a built-in equivalent of
@always_seq(clk.posedge, rst) for synchronous sets, is the following best
practice? Let me know if it's bad practice to embed html.

def qff_w_set(clk, set, q0, q, d):

  @always_seq(clk.posedge)
  def logic():
    if set:
      q.next = q0
    else:
      q.next = d

  return logic

Thanks,
Colin

Yes, that is a reasonable approach.
