1-10-5: IC Layout Tutorial: Constraints |
Select a wire and issue the Rigid command (in menu Edit / Arc). The letters change to "R" on the arc and the wire no longer stretches when nodes move. Find another arc and issue the Not Fixed-angle command. Now observe the effects of an unconstrained arc as its neighboring nodes move. These arc constraints can be reversed with the Rigid and Fixed-angle commands. See Section 5-2-1 for more on these constraints.
