- New Feature : to allow routing reuse, NeRo is now able to build the abstract of a mega-cell. That is, adds the relevant CALUx and TALUx describing the interface at top-level. - Bug : in the abstract generation, the intermediates TALUx metals of a stacked VIA where forgotten. For example, when there is a VIA34 on top of a VIA23 you must have obstacles in TALU4 and TALU2 but also a "dot" obstacle in TALU3. "Dot" obstacle are added only when we process a layer in the preferred routing direction, otherwise we would create a dot at each routing grid point... |
