Routing Command Synthesizer

ⓘ Run Generate first to load grouped suggestions for Start point, End point, and Track coordinate from the current design (instances, pins, and pointers). Click the ▾ button next to a field to browse.

Command type:

Grid:

Via at start:

Via at end:

Net name (optional):

Auto-connect pointer offsets (route_pointer_offset)

Generates: dsn.route_p2p(mn=[start, end], via_tag=[...], netname='...'). Adds route_pointer_offset=True when the checkbox is set.

Net name:

Default pointers:

Type a net name above to list matching pins (run Generate first).

Track orientation:

Vertical Horizontal

Track coordinate:

Auto-connect pointer offsets (route_pointer_offset)

Nodes:

Nodes to include:

Nodes to exclude:

Generates: dsn.route_net(netname='...', track=[v, None]) (or [None, v] for horizontal). Adds route_pointer_offset=False when the checkbox is cleared. nodes/nodes_include/nodes_exclude are appended as kwargs only when filled.
