Parses odb++ files to give a human readable JSON representation of a board layer. Currently only parses features and netlist files.
Built against the ODB++ Format Specification Version 8.1 (Sept. 2015), available here: http://www.odb-sa.com/resources/
You'll need Ruby 2.0+. Install dependencies:
bundle install
Output will be sent to stdout
To parse the board:
ruby main.rb layer sample/features sample/netlist sample/components
{
"nets": [],
"components": [],
"pads": []
}To parse the sample/features file:
ruby main.rb features sample/features
{
"pads": [
{
"id": "209",
"symbol": {
"type": "round",
"diameter": "55"
},
"x": "1.59",
"y": "0.1"
},
{
"id": "312",
"symbol": {
"type": "oval",
"width": "24",
"height": "74"
},
"x": "1.64",
"y": "0.66"
},
{
"id": "346",
"symbol": {
"type": "square",
"side": "70"
},
"x": "0.25425295",
"y": "0.69755837"
}
]
}To parse the sample/netlist file:
ruby main.rb netlist sample/netlist
{
"nets": [
{
"name": "GND",
"points": [
{
"x": "1.72",
"y": "0.56"
},
{
"x": "1.14",
"y": "0.41"
},
{
"x": "1.59",
"y": "0.1"
},
{
"x": "1.64",
"y": "0.56"
},
{
"x": "1.64",
"y": "0.51"
},
{
"x": "0.2552531",
"y": "0.2975584"
},
{
"x": "1.2197234",
"y": "0.4059187"
},
{
"x": "1.5294807",
"y": "0.1026173"
}
]
}
]
}This includes net information for each pad:
To parse the layer:
ruby main.rb layer sample/features sample/netlist
{
"pads": [
{
"id": "90",
"symbol": {
"type": "round",
"diameter": 55.0
},
"x": 1.94,
"y": 0.36,
"net": "+5V"
},
{
"id": "96",
"symbol": {
"type": "round",
"diameter": 55.0
},
"x": 1.52,
"y": 0.56,
"net": "+5V"
},
{
"id": "100",
"symbol": {
"type": "round",
"diameter": 55.0
},
"x": 1.41,
"y": 0.1,
"net": "+5V"
}
]
}To run tests:
rspec
Currently it can identify these entities:
- round
- square
- rectangle
- oval
- pads
- lines
- net_name
- serial_num
- net_num
- radius
- x
- y
- side
- w (optional)
- h (optional)
- epoint
- exp
- CMP records (components)
- PRP records (properties)
- TOP records (toeprints)
