Definitions¶

VirtualPinParams¶

Pin Statement Optional Parameters

public defstruct VirtualPinParams <: Equalable :
    direction: Dir
    pad-ref-size: Maybe<Double>
    pin-length: Double
    pin-name-size: Maybe<Double>

direction: Dir
pad-ref-size: Maybe<Double> - Pad Id/Ref Text Size This parameter is optional and if set to None then no pad Ref text will be generated
pin-length: Double
pin-name-size: Maybe<Double> - Pin Name Text Size This parameter is optional and if set to None then no pin name text will be generated

The pin statement in a pcb-symbol can be a standalone point or it can have some parameterization. This struct defines the parameterization so that the user can optionally include this in pin definitions.

Functions¶

VirtualPinParams¶

public defn VirtualPinParams ( -- direction:Dir, pin-length:Double, pad-ref-size:Double = ?, pin-name-size:Double = ?) -> VirtualPinParams

Returns VirtualPinParams

add-pin¶

public defn add-pin (sn:SymbolNode, pin-name:String|Ref, position:Point|[Double, Double]|[Int, Int] -- params:VirtualPinParams = ?, name:String = ?, class:Seqable<String>|String = ?) -> VirtualPin

Returns VirtualPin

VirtualPin¶

public defn VirtualPin (pin-name:String|Ref, position:Point -- params:Maybe<VirtualPinParams> = ?, decorators:Seqable<PinDecorator> = ?, name?:Maybe<String> = ?, class:Seqable<String>|String = ?) -> VirtualPin

Returns VirtualPin

SymbolElement¶

Base Type for all SymbolNode types

public deftype SymbolElement <: Classable

Functions¶

elements¶

public defn elements (sn:SymbolNode) -> Seq<SymbolElement>

Returns Seq<SymbolElement>

PinDecorator¶

Pin Decorator - add art to a pin

public defstruct PinDecorator <: SymbolElement :
    art: Shape

art: Shape - Art to apply to the pin The shape defined here will be applied in a frame of reference where the pin's position is the origin. It is assumed that the pin is pointed to the Left when drawing the art. The art shape will be flipped across the Y axis for Right pins. For the Up pins, the Left pin version is rotated 90 degrees. For the Down pins, the Right pin is rotated 90 degrees.

This type is used to construct shapes that are used to indicate special functions for pins.

For Example:

Bubble for active-low indication
Arrows for Input / Output
Open-Drain Indicator
Clock Angle Symbol

Functions¶

VirtualPin¶

public defn VirtualPin (pin-name:String|Ref, position:Point -- params:Maybe<VirtualPinParams> = ?, decorators:Seqable<PinDecorator> = ?, name?:Maybe<String> = ?, class:Seqable<String>|String = ?) -> VirtualPin

Returns VirtualPin

PinDecorator¶

public defn PinDecorator (art:Shape -- name?:Maybe<String> = ?, class:Seqable<String>|String = ?) -> PinDecorator

Returns PinDecorator

add-decorator¶

Add a decorator to this pin

public defn add-decorator (vp:VirtualPin, dec:PinDecorator)

User can add multiple decorators to a pin. Current implementation doesn't handle preventing overlap well.

add-decorator¶

public defn add-decorator (vp:VirtualPin, decs:Seqable<PinDecorator>)

SymbolNode¶

Scene Graph Builder for Schematic Symbols

public defstruct SymbolNode <: SymbolElement :
    backend-sub?: Vector<KeyValue<String, SchematicSymbol>>
    children: Vector<SymbolNode>
    glyphs: Vector<Glyph>
    parent: Maybe<SymbolNode>
    pose: Pose
    preferred-orient?: Maybe<SymbolOrientation>
    scale: Maybe<Double>
    vpins: Vector<VirtualPin>

backend-sub?: Vector<KeyValue<String, SchematicSymbol>> - Backend Symbol Substitutions This vector holds a mapping of name to substitute symbols. The name parameter is the backend name like Altium or Kicad The substitute symbol is a pcb-symbol definition that will replace the symbol generated by this generator when exported to the proposed backend.
children: Vector<SymbolNode>
glyphs: Vector<Glyph>
parent: Maybe<SymbolNode>
pose: Pose
preferred-orient?: Maybe<SymbolOrientation> - Optional Preferred Orientation This parameter is only applicable for the root node of the symbol scene graph. This generates the preferred-orientation statement in the symbol context if not None()
scale: Maybe<Double> - Converts from Symbol grid to millimeters When we create schematic symbols, we often like to construct elements of that symbol with respect to a grid. For example, we might want all of the pins on a 100mil grid. This makes all of the symbols consistent and leads to a nicer aesthetic.

This parameter is used to enforce a grid scaler so that when we construct pins and glyphs, we can use simple units.

The default scale converts 1.0 -> 2.54mm -> 100mil
vpins: Vector<VirtualPin>

The SymbolNode is a node in the scene graph for a schematic symbol. The idea is that we can construct a symbol by combing various leafs that are transformed from the root node. This allows for grouping content and simplifying the calculations needed to combine various forms of content.
