Thank you! Will Quartus-II 8.0 support unnamed-block variable-declarations? (The example below causes syntax-error in Quartus-II 7.1 April 2007.) always_comb begin for ( int i = 0; i < 256; ++i ) my_array[i] = in_a[i] + in_b[i]; end "Subroto Datta" <sdatta@altera.com> wrote in message news:1180985053.020785.303430@a26g2000pre.googlegroups.com...> On May 27, 10:12 pm, "Xilinx user" <xilinx_u...@nowhere.net> wrote: >> DoesQuartus-II 7.1 support theSystemverilogpreprocessor's `` >> concatenator? >> >> `define pori_reg(r) \ >> r <= def_``r >> ... > > No, Quartus II does not support any of the `define extensions defined > by the SystemVerilog language.
