tyndall_packaging.all.PackagingArray

class tyndall_packaging.all.PackagingArray

Packaging array where each grating can be different.

The array is parametrised in such a way that you should be able to make all the configurations supported by EUROPRACTICE packaging. The packaging array automatically checks for a large number of package design rules.

Parameters:

out_name: str and String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters

name of the out port in the grating classes

n_o_south_bondpads: int and number >= 0 and [0,11[

Number of south_bondpads

n_o_north_bondpads: int and number >= 0 and [0,11[

Number of north_bondpads

west_gratings: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>

Lists of gratings used in the west

east_gratings: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>

Lists of gratings used in the east

shunt_grating_east: PCell

Shunt grating used on the east

shunt_grating_west: PCell

Shunt grating used on the west

bondpad: ( PCell ), *None allowed*

bondpad used

name: String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters

The unique name of the pcell

Other Parameters:

n_o_user_west_gratings: int and number >= 0 and List with value restriction, allowed values: [0, 1, 8, 14], locked

Number of user gratings - without the shunt gratings.Same length as west gratings

n_o_user_east_gratings: int and number >= 0 and List with value restriction, allowed values: [0, 1, 8, 14], locked

Number of user gratings - without the shunt gratings. Same length as east_gratings
