A method for curing antenna violations on an integrated circuit that includes multiple levels includes: obtaining a design of a circuit, the design including a first element connected to first device and a second element connected to one or more second devices, wherein the first and second elements both receive a common signal; determining that an antenna violation exists in on the first element at a first level of the multiple levels; and modifying the design of the circuit to add a connected between the first element and the second element at the first layer or at a layer below the first layer.

Method to cure antenna violations in clock network using jumpers

Embodiments of the invention include protecting against antenna violations in a macro having a clock mesh. Aspects include obtaining a design of the macro, the design including a clock layer having a plurality of clock pins and determining a longest vertical wire and a longest horizontal wire allowed based on a design of the clock mesh. Aspects also include identifying, based at least in part on the longest vertical wire and the longest horizontal wire, a plurality of checkbox regions for a clock pin of the plurality of clock pins and calculating a total diffusion area for each of the plurality of checkbox regions. Aspects further include adding, to the design of the macro, an antenna diode to the clock pin based on a determination that the total diffusion area for any of the plurality of checkbox regions is less than a threshold value.

Predictive antenna diode insertion in a macro having a clock mesh

An adjustable window blind cord stopper includes a locking guider slidably connected on a lift cord of the window blind assembly by constructing an adjustable knot at a guiding through slot of the locking guider. In which, in an unlocked position that the adjustable knot is normally loosen with respect to the locking guider, the cord stopper is adapted for sliding along the cord in such a manner that when the adjustable knot is positioned above the guiding through slot, the cord stopper is adapted to slide downwardly along the lift cord, and when the adjustable knot is positioned below the guiding through slot, the cord stopper is adapted to slide upwardly along the lift cord. Thereby, the folding or unfolding condition of the slats of the window blind assembly can be locked up by sliding the cord stopper between an upper position and a lower position.
