Crate pedalkernel_layout 

Automatic schematic layout engine for PedalKernel .pedal circuits.

Converts a parsed pedalkernel::dsl::PedalDef into a positioned layout suitable for:

1. Plugin UI — real-time signal flow visualization with monitor-driven glow
2. KiCad export — properly placed .kicad_sch files for PCB design

Pipeline

PedalDef
  → LayoutGraph        (directed graph with pin-direction inference)
  → FunctionalGroups   (gain stages, tone stacks, push-pull, etc.)
  → Column assignment  (Sugiyama layering for left-to-right signal flow)
  → Vertical placement (supply → signal path → ground convention)
  → Wire routing       (orthogonal Manhattan paths)
  → Optimization       (crossing minimization, grid snap, symmetry)
  → Layout             (JSON-serializable output)

Modules

graph

Phase 1: Directed graph construction from the .pedal netlist.

groups

Phase 2: Functional group detection.

kicad

KiCad .kicad_sch schematic export from layout data.

layering

Phase 3: Sugiyama layer (column) assignment.

optimize

Phase 6: Aesthetic optimization pass.

placement

Phase 4: Vertical placement within columns.

routing

Phase 5: Wire routing (orthogonal Manhattan paths).

symbols

Component symbol definitions.

types

Output types for the schematic layout engine.

Functions

generate_layout
