lepton-symcheck - Lepton EDA Symbol Checker


lepton-symcheck [-h] [-v] [-q] symbol1 [...symbolN]


lepton-symcheck is a symbol checker for Lepton EDA. Here is a list of checks that lepton-symcheck performs:

Checks for graphical attribute (if present does varied tests)
Checks for the device attribute
Checks for various other missing attributes (pinlabel, pintype, pinseq, footprint, refdes)
Checks to make sure that the active pin end is on the 100 unit grid.
Checks the uses of the various attributes (duplicates, incorrect syntax, invalid values, etc...)
Checks for obsolete, old, and forbidden attributes
Checks for any nets or buses within a symbol
Checks for any other connections within a symbol
Checks to make sure the number of pins is the correct number


lepton-symcheck accepts the following options:
-q, --quiet
Quiet mode on. This mode turns off all warnings/notes/messages. (optional)
-v, --verbose
Verbose mode 1. This mode will show all error messages (optional)
Verbose mode 2. This mode will show all error and warning messages (optional)
Verbose mode 2. This mode will show all error, warning, and info messages (optional)
-h, --help
Usage summary / lepton-symcheck help
symbol1 [...symbolN]
At least one symbol file must be specified. If multiple symbols are specified then they are sequentially read in and checked. It is important that the schematic(s) follow all the options (i.e. last).


Here are some examples on how to run lepton-symcheck:

To get usage information just run:


To actually check a symbol with just error counts, run:

lepton-symcheck symbolfilename.sym

To get the actuall error messages, run:

lepton-symcheck -v symbolfilename.sym

To see all the error messages and warnings, run:

lepton-symcheck -vv symbolfilename.sym

To see all the error messages, warnings, and parse info, run:

lepton-symcheck -vvv symbolfilename.sym


lepton-symcheck respects the following environment variable:
specifies where the various required scheme and rc files are located (the default is ${prefix}/share/lepton-eda). This environment variable does not need to be set by the end user unless they are moving the executables to a new install ${prefix}.
