Verilog Format

Console application for apply format to verilog file.

How to use

Application options:

usage: [java -jar verilog-format.jar|./verilog-format|verilog-format.exe]
       [-f <pathname>] [-h] [-p] [-s <verilog-format.properties>] [-v]
 -f,--format <pathname>                      verilog file
 -h,--help                                   print this message
 -p,--print                                  print file formated
 -s,--settings <verilog-format.properties>   settings config
 -v,--version                                verilog-format version

Examples

## Print input_file.v formatted
$ ./verilog-format -p -f input_file.v -s verilog-format.properties 

## Format input_file.v
$ ./verilog-format -f input_file.v -s verilog-format.properties

## Format input_file.v
## If .verilog-format.properties exist in project folder, this is used,
## otherwise default setting is used..
$ ./verilog-format -f input_file.v
