Default Re: How to handle the high fanout

Is the regenr and the regenr2 have the diffient load, or I think you
can set the maxfan attribute in your hdl sourse file?For
example(verilog)
reg regenr /*synthesis syn_maxfan=32*/;//32 is the max fanout
that for example you can add yours instead than the synthesis tools
will auto duplicate the registers.also you can set the maxfan for all
in the synthesis tool,you can look the synplify online help.
Best regrads!
