Re: [sv-ac] Updated proposal for 3069

I think that it would be a good idea to add a note on how to handle global
clocking using parameters, as we discussed at our meeting:

       parameter P;
       generate
          if (P==1) begin:b1
               assign gen_clk = clk1;
           end
           else begin:b1
               assign gen_clk = clk2;
           end
       endgenerate

       global_clocking b1.gen_clk;
