verilog diff，按verilog语法做diff。 ------------------------------------------------- usage: vdiff [options] file1 file2 layout: -u, -U N, --unified[=N] unified (top/bottom) output, N context lines [3] -c, -C N, --context[=N] context output, N context lines [3] -y, --side-by-side side by side (left/right) output -W N, --width=N width of the side by side output [130] --suppress-common-lines with -y: only show the lines that differ (default: normal diff output) comparison: -i, --ignore-case compare tokens case insensitively --show-comments include comments in the comparison -s, --report-identical-files report when the files are identical -q, --brief report only whether the files differ -w -b -B -E -Z --ignore-all-space --ignore-space-change accepted for compatibility (always ignored) labels: -L, --label LABEL use LABEL instead of the file name (twice) comparison mode: -a, --text compare as plain text (one unit per line, whitespace and comments significant), i.e. what "diff" does - no Verilog structure at all --no-fallback keep the statement based diff even when a file looks broken (a warning is still printed) syntax: --check only report structural problems, do not diff (unbalanced brackets, missing ';', lost 'endmodule'); exit 1 when something is wrong --strict fail with exit 2 when a file has structural problems, instead of warning and diffing --no-check do not run the structural checks exit status: 0 same, 1 different, 2 trouble
