Build

python build.py my_output_dir_symbols my_output_dir_footprints

Where,

• my_output_dir_symbols is in the geda gafrc file
• my_output_dir_footprints is in the geda pcb .prj file

Folder usage

• footprints/fp/ - for manually crafted *.fp files
• footprints/gen/ - for mk_*.py generators (used to auto generate *.fp files)
• symbols/sym/ - for manually crafted *.sym files
• symbols/tsv/ - for *.tsv files (used to auto generate *.sym files)

To Do List - up for discussion

1. fp gen - Support for arrays of pins/pads - should be able to do a whole row in one function call
2. fp gen - REFDES text and better positioning of REFDES text - better footprint metadata
3. fp gen - Support for two-way and four-way symmetrical arrays of pins and pads
4. use a footprint family generator such as: mk_QFN-N.py, mk_WFDFN-N.py, mk_SOIC-N.py, mk_SSOP-N.py, mk_TSSOP-N.py, mk_HTSSOP-N.py, mk_WSOP-N.py, mk_BGA-N.py, mk_uSIP-N.py, mk_CONN*.py, mk_RADIAL*.py, mk_pe*.py, mk_holes.py
5. Naming standard for family generators - perhaps postfix with "-N"
6. w/x vs l/h/y definition/clarification - perhaps vertical/horizontal or stick with x/y standard coordinated frame: x = left/right, y = up/down
7. Merge mk_peSOT23_GSD.py and mk_SOT23_3.py
8. .sym generator (replacing .tsv) - particular for families
9. .sym to match manufacturer part number - likely the high level .sym generator should produce all names in the family
10. Check hole sizes - seems tight
11. Produce ruler for checking footprints
12. Add comment to link datasheet (to clarify dimensions)
13. More standardization:
    • uppercase vs lowercase
    • • vs _
    • should / characters be replaced with -
14. Should connectors show the minimal outline and maximum outline (e.g. plug) - or perhaps two different footprints depending on size objectives
15. Enforce 80 char line limit?
16. Increase pin clearance suitable for pcbway design rules
17. Ensure CONN prefix for all connectors - e.g. usb
18. Ensure footprints pads are larger then part pads
19. Ensure sch part pin spacing is 500
20. Ensure CONN 0,0 is at pin 1
21. Prefix SMT CAPs with CAP-SMT
22. Remove old radials scripts and use mk_RADIAL.py only
23. Cleanup usb sym's - pin number depends on USB version and connector type.
24. ensure bom created can handle part names with ,
