IMPLICIT NONE

! Gschem (for Ngspice) symbol parameters:
! parameters which define the size of the circuit symbol
! all parameters are defined in mils (1/1000 of an inch)
! see http://wiki.geda-project.org/geda:file_format_spec

! x extent of symbol - this is fixed
integer,parameter    :: xmin_symbol    =200
integer,parameter    :: xmax_symbol    =1800

! y extent of symbol varies with the numbe of conductors
integer,parameter    :: ymin_symbol    =000

integer,parameter    :: ymin_offset    =100
integer,parameter    :: ymax_offset    =100
integer,parameter    :: ymax_text_offset =200

! separation of the conducor pins in the y direction
integer,parameter    :: y_conductor_spacing    =200

! length of connection pins in the x direction
integer,parameter    :: x_pin_length        =200

! We need to check the version number - how do we specify this? Is it related to the version of gEDA?
character(LEN=12),parameter    :: symbol_version='v 20050820 1'


! LTpsice symbol parameters:
! parameters which define the size of the circuit symbol

! It appears that the grid used in the LTspice scematic capture uses a grid with spacing 16 points
! so distances here should be a multiple of 16 points.

! x extent of symbol - this is fixed
integer,parameter    :: LT_xmin_symbol    =16
integer,parameter    :: LT_xmax_symbol    =192

! y extent of symbol varies with the numbe of conductors
integer,parameter    :: LT_ymin_symbol    =00

integer,parameter    :: LT_ymin_offset    =16
integer,parameter    :: LT_ymax_offset    =16
integer,parameter    :: LT_ymax_text_offset =32

! separation of the conducor pins in the y direction
integer,parameter    :: LT_y_conductor_spacing    =32

! length of connection pins in the x direction
integer,parameter    :: LT_x_pin_length        =16

! We need to check the version number - how do we specify this?
character(LEN=9),parameter    :: LT_symbol_version='Version 4'
