Number of Inverters

[Mbonea-Mjema]

Hello,

I was trying to get the xmg circuit from the verilog file, I noticed that the number of inverters are more than the number I got from the xmgcost command, I tried this with the EPFL benchmarks. I also tried to use xmginv to optimize the number of inverters, but I got the same verilog file in the output as before the inverter optimization.

without the xmginv

    read_aiger $i; ps -a;
    lut_mapping;
    convert --aig_to_mig; ps -m;
    convert --mig_to_xmg; ps -x;
   write_verilog -x $destination_path/${strarr[5]}.v;

with the xmginv

    read_aiger $i; ps -a;
    lut_mapping;
    convert --aig_to_mig; ps -m;
    convert --mig_to_xmg; ps -x;
    xmginv
    write_verilog -x $destination_path/${strarr[5]}.v;
