Execute(The default verilator command should be correct):
  AssertLinter 'verilator', 'verilator --lint-only -Wall -Wno-DECLFILENAME -I%s:h  %t'

Execute(verilator options should be configurable):

  let g:ale_verilog_verilator_options = '-sv --default-language "1800-2012"'

  AssertLinter 'verilator', 'verilator --lint-only -Wall -Wno-DECLFILENAME -I%s:h -sv --default-language "1800-2012" %t'
