Summary:Global routing techniques for an automated analog/digital IC
layout compiler are presented. The global router routes in a net-by-net,
high-sensitivity-net-first order. Minimum trees are searched for the
interconnection of sensitive nets and power nets. For the routing of
noise nets, the router provides a net-crossing-free terminal assignment
between sensitive nets and noise nets for the routing of channels.
Efficient terminal assignment and extraction techniques for the router
are also presented
