gEDA-user: Register enables in Icarus

[David Howland]

Say I want to make a clocked, enabled register.  This would simply be 
the following in behavioral verilog:

    always @(posedge clk) begin
    if (en) begin
      Q <= D;
    end
    end
That verilog will work with most tools, but it seems to me that if I 
want to use Icarus synthesis, I have to change the code to the following:

    always @(posedge clk) begin
    if (en) begin
      Q <= D;
    end else begin
      Q <= Q;
    end
    end
However, this doesn't really describe a register with an enable signal. 
 Is this making any sense?
Thanks for any insights.
