Function Documentation

int plcc_create_element (  ) 
int plcc_create_packages_list (  ) 

Create a list of known PLCC packages.

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

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

Definition at line 508 of file plcc.c.

int plcc_drc (  ) 

Do some Design Rule Checking for the PLCC package type.

  • 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 minimum clearance between pad copper and fiducial pad copper (including solder mask clearances).
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 plcc_get_default_footprint_values (  ) 

Look up default values for PLCC 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:
-.

Returns:
EXIT_SUCCESS when default values for a footprint were found, EXIT_FAILURE when the footprint name was not found.

int plcc_set_gui_constraints (  ) 

Set GUI constraints for the PLCC package type.

This function is only to be compiled for GUI targets.

Returns:
EXIT_SUCCESS when the function is completed.
