I have chosen to undertake VLSI CAD as a part of my electronics degree and I came across this statement (Source : Naveed Sherwani, Algorithms for VLSI Physical Design Automation, 3rd edition , Chapter 8. Global Routing , Page 251) :

the statement

I had an issue in understanding as to why channels and 2d switchboxes are routed first. I cannot comprehend what it is trying to convey.

  • \$\begingroup\$ @VoltageSpike I did not understand what that statement even implied (why are 2d and channel routed first) \$\endgroup\$
