Component parameters

These parameters may determine the value of the component, whether the component is shown as placed or not placed, etc.

place parameter

Example:

import lib
v5v = supply("5V")
gnd = dgnd()

C1 = cap(100n)

at v5v
wire down 100
add C1
wire down 100
to gnd

C1.place = false

frame:
    at v5v
    wire down 100
    add cap(100n)
    ..place = false
    wire down 100
    to gnd

Double dot operator

The double dot operator (..) can be used to modify parameters at the current cursor point. In the example below, pin 1 of C1 is the cursor point before the double dot. This operator can be used to reference components without assigning specific variable names to them.

Example

import lib

frame:
    ..title = "Setting parameter with variable name"

    my_cap = cap(100n)
    at my_cap
    my_cap.place = false

frame:
    ..title = "Setting parameter with double dot operator"

    at cap(100n)
    ..place = false

Supported component parameters

Parameter name	Parameter type	Description
place	boolean	When true, the component will be shown as placed in the schematic. If set to false, a cross will be displayed on the schematic.
footprint	string	Path or name of the footprint file/data.
mpn	string	Manufacturer part number for the component
value	string/numeric value	For typical passive components (resistors, capacitors and inductors), you may use numeric values like: 10k, 20n, etc.
refdes	string	Set the reference designator for the component manually.

Example:

import lib

v5v = supply("5v")
gnd = dgnd()

at v5v
wire down 100

add res(20k)
..value = 30k   # Change the value of resistor
..mpn = "res-123456"

wire down 100
to gnd
