REGISTER_FUNCTIONS ( sil_function_list )

A list containing all SIL related functions.

Initialise by registering all SIL related functions.

Definition at line 1026 of file sil.c.

int sil_create_element ( )

Create an Element for a SIL package.

Returns:: EXIT_SUCCESS when an element was created, EXIT_FAILURE when errors were encountered.

Definition at line 36 of file sil.c.

Here is the call graph for this function:

int sil_create_packages_list ( )

Create a list of SIL packages with pre-defined values.

The data in this list can be used in a combo box to select a pre-defined package.

Returns:: EXIT_SUCCESS when a packages list was created, EXIT_FAILURE when errors were encountered.

Definition at line 327 of file sil.c.

int sil_drc ( )

Do some Design Rule Checking for the SIL package type.

check for number of rows is > 1.
check for number of columns is more than 1.
check for allowed pad shapes.
check for zero sized packages.
check for a zero sized courtyard.
check for minimum clearance between copper (X-direction).
check for minimum clearance between copper (Y-direction).
If any fiducials exist:
- check for zero fiducial pad diameter.
- check for zero width solder mask clearance.
- check for minimum clearance between copper (between pads and fiducials, if any fiducials exist).
check for clearance of the package length with regard to the courtyard dimensions.
check for clearance of the package width with regard to the courtyard dimensions.
check for any silk lines or texts touching bare copper.
check for soldermask clearance (solder mask overlapping copper at the solder fillet area or worse).
check for a reasonable silk line width.

Returns:: EXIT_SUCCESS when no DRC violations were encountered, EXIT_FAILURE when DRC violations were found.

Todo:: Check for any silk lines or texts touching bare copper.

Todo:: Check for soldermask clearance (solder mask overlapping copper at the solder fillet area or worse).

int sil_get_default_footprint_values ( )

Look up default values for SIL footprints.

Footprint values can be looked up by placing a question mark "?" in front of the footprint name.
If the footprint name is recognised the values will be loaded and the entries involved in the GUI will be updated accordingly.
Currently the following footprints are supported:
