ChecksConfig

Configuration for design checks.

Controls tolerances for port connectivity checks (position, angle, width) and bend radius validation. Pass to run_checks() to customize checking behavior.

config = ChecksConfig(
    position_tolerance=0.001,
    angle_tolerance=0.1,
    check_widths=True,
    min_bend_radius=5.0,
    severity="error",
)
result = run_checks(cell, config=config)

Methods

func__init__(position_tolerance=0.001, angle_tolerance=0.1, check_widths=True, min_bend_radius=None, severity='error') -> None

Create a new checks configuration.

paramposition_tolerancefloat

= 0.001

Maximum gap between port centres (in design units) to count as connected. Ports closer than this distance are considered a valid connection.

paramangle_tolerancefloat

= 0.1

Maximum angular deviation from anti-parallel (in degrees) to count as a valid connection. Two ports must face each other within this tolerance.

paramcheck_widthsbool

= True

Whether to flag width mismatches between connected ports. When enabled, connected ports with different widths generate a violation.

parammin_bend_radiusfloat | None

= None

Minimum allowed bend radius in design units. Set to None to skip bend radius checking. When set, bends recorded in cell metadata are validated against this limit.

paramseveritystr

= "error"

Default severity for violations: "error" or "warning".

Returns

None
