Hi all,

Will these 2 giving a same output?

bufif1 (weak0,weak1) G1 (A11,1'b0,DATAR);
bufif1 (weak0,weak1) G2 (A11,1'b0,DATAR);
 

Yes, Verilog does not add drive strengths together, nor does it reduce strengths based on how much fanout the signal has.
 

then, how about
bufif1 (weak0,weak1) G1 (A11,1'b0,DATAR);
bufif1 (weak1,weak0) G2 (A11,1'b0,DATAR);

any different for these 2?
