Thank you for sharing! Can you provide the code to generate score based on iccad2017 competition scoring standard?

Truncation of output def for large designs

Hi,

I noticed that for large designs, the output def is often truncated as a result of the parser.write_def function found in parser.cpp. On my installation I added a fclose(fileOut); on the line following the closing brace on 2131, before printing the success message, which fixed this issue. Specifically...

OpenDP/src/parser.cpp

Line 2131 in 7f92fe3

}

      fwrite( line.c_str(), line.length(), 1, fileOut );
    }
  }
  fclose(fileOut); 
  cout << " DEF file write success !! " << endl;

Floating point exceptions on provided benchmarks

Hi there,

I can't seem to get the provided benchmarks to run on a fresh build of your detailed placer.

Specifically, the command (from the OpenDP/build directory containing the opendp executable) is:

$./opendp -lef ../bench/benchmarks/pci_bridge32_a_md1/cells_modified.lef -def ../bench/benchmarks/pci_bridge32_a_md1/placed.def -output_def test.out.def

The output is:

Although this pci bridge case was chosen, several examples fail with the same error.
