Problems using "generate" and "genvar" w

[Chanquete]

Hi,

I have generated the verilog code copied at the end of this message. When compiling with ncverilog I get the following eror:

.ref(ref[col_gen*8 +: 8]),
|
ncelab: *E,RNOTCX (..\full\full_me_reg2.v,264|2: illegal use of a real number
as part of an expression.
.ref(ref[col_gen*8 +: 8]),


It seems that ncverilog has problems with generate statements. Anyone can help me? Thanks a lot in advance!!!

Best!
--------------------------------------------------------------------

genvar row_gen, col_gen;

generate

for(row_gen=0; row_gen<8; row_gen=row_gen+1)
begine_row
for(col_gen=0; col_gen<8; col_gen=col_gen+1)
begine_col_l
pe_full u_pe_full (
.rst_n(rst_n),.clk(clk),
.ref(ref[col_gen*8 +: 8]),
.enable_ref(enable_ref[row_gen]),
.enable_search(enable_search[row_gen]),
.sel(sel[row_gen]),
.search(search[col_gen*8 +: 8]),
.previous_pe(next_pe[128*(row_gen+1)+col_gen*8 +: 8]),
.next_pe(next_pe[128*row_gen+col_gen*8 +: 8]),
.sum_in(adder_l[144*row_gen+col_gen*16 +: 16]),
.sum_out(adder_l[144*row_gen+(col_gen+1)*16 +: 16]));
end
for(col_gen=8; col_gen<16; col_gen=col_gen+1)
begine_col_r
pe_full u_pe_full (
.rst_n(rst_n),.clk(clk),
.ref(ref[col_gen*8 +: 8]),
.enable_ref(enable_ref[row_gen]),
.enable_search(enable_search[row_gen]),
.sel(sel[row_gen]),
.search(search[col_gen*8 +: 8]),
.previous_pe(next_pe[128*(row_gen+1)+col_gen*8 +: 8]),
.next_pe(next_pe[128*row_gen+col_gen*8 +: 8]),
.sum_in(adder_m[144*row_gen+(col_gen-*16 +: 16]),
.sum_out(adder_m[144*row_gen+(col_gen-8+1)*16 +: 16]));
end
end
endgenerate

Re: Problems using "generate" and "genvar&amp

Checkout this some bracket was missing....

genvar row_gen, col_gen;

generate
   for(row_gen=0; row_gen<8; row_gen=row_gen+1) begin:pe_row
      for(col_gen=0; col_gen<8; col_gen=col_gen+1) begin:pe_col_l
         pe_full u_pe_full (

                            .enable_search (enable_search[row_gen]),

      end

Many thanks, but this code also does not seem to work
