# SN-L00 Autorouting Script using Freerouting
|
|
#
|
|
# Usage:
|
|
# ./autoroute.sh # Uses default paths
|
|
# ./autoroute.sh input.dsn # Custom input file
|
|
# ./autoroute.sh input.dsn output.ses
|
|
#
|
|
# Prerequisites:
|
|
# 1. Export DSN from KiCad: File → Export → Specctra DSN
|
|
# 2. Java runtime installed
|
|
#
|
|
# After running:
|
|
# Import the .ses file in KiCad: File → Import → Specctra Session
|
