Sheets

The sheet keyword can be used to group circuits into different sheets based on standard paper sizes. At the start of the script, specify the type of sheet with the following code: document.sheet_type = <sheet_type_function>().

The standard library supports the following sheet_type_functions: sheet_A1(), sheet_A2().. until sheet_A6()

Example:

import lib

# Set default sheet type to A6
document.sheet_type = sheet_A6()

vcc = supply("VCC")
gnd = dgnd()

# Sheet created with sheet A6 graphic
sheet:
    ..title = "Pull down resistor"
    at vcc
    wire down 100
    add res(10k)
    wire down 100
    to gnd

# Another sheet with sheet A6 graphic
sheet:
    ..title = "Decoupling capacitor"
    at vcc
    wire down 100
    add cap(100n)
    wire down 100
    to gnd

Sheet properties

Supports the title and direction property, similar to the frame command.

Additionally, the revision property is also available. This appears in the sheet title block and can be used to indicate the version of the schematic design.

import lib

# Set default sheet type to A6
document.sheet_type = sheet_A6()

vcc = supply("VCC")
gnd = dgnd()

# Sheet created with sheet A6 graphic
sheet:
    ..title = "My schematic"
    ..direction = "column"
    ..revision = "V1.2"

    at vcc
    wire down 100
    add res(10k)
    wire down 100
    to gnd

    at vcc
    wire down 100
    add res(10k)
    wire down 100
    to gnd

    at vcc
    wire down 100
    add res(10k)
    wire down 100
    to gnd

Sheet layout

Circuits placed within a sheet will try to stay within the sheet area and will avoid being placed over the title block.

import lib

# Set default sheet type to A6
document.sheet_type = sheet_A6()

vcc = supply("VCC")
gnd = dgnd()

def led_circuit():
    at vcc
    wire right 200 
    add led("green")
    wire right 100
    add res(1k)
    wire right 100
    to gnd

# Sheet created with sheet A6 graphic
sheet:
    ..title = "Lots of LEDs"
    ..revision = "V1.2"

    for i in range(0, 16):
        led_circuit()
