KLayout Display Skills

Toggle layer visibility in KLayout via the MCP server for better visualization during design review.

Prerequisites

• KLayout running with KlayoutClaw plugin (v0.3+)
• A layout with layers must be open

Script

toggle_layer.py — Toggle layer visibility

python scripts/toggle_layer.py <layer> <datatype> [on|off]

• on — make layer visible
• off — make layer invisible
• Omit to toggle current state

Examples:

python scripts/toggle_layer.py 1 0 off    # hide mesa layer
python scripts/toggle_layer.py 2 0 on     # show metal layer
python scripts/toggle_layer.py 3 0        # toggle bonding pads

show_only.py — Show only specified layers, hide all others

python scripts/show_only.py <layer1/dt1> [<layer2/dt2> ...]

Example:

python scripts/show_only.py 1/0 2/0      # show only mesa + metal, hide pads

How It Works

The scripts use execute_script to manipulate pya.LayerProperties in the current LayoutView. Each layer properties entry has a visible attribute that controls display.

For custom display manipulation beyond these scripts, use execute_script directly:

tool_call("execute_script", code="""
lp_iter = _layout_view.begin_layers()
while not lp_iter.at_end():
    lp = lp_iter.current()
    lp.visible = (lp.source_layer == 1)  # show only layer 1
    _layout_view.set_layer_properties(lp_iter, lp)
    lp_iter.next()
""")
