Timing-driven placement based on monotone cell ordering constraints
− In this paper, we present a new timing-driven placement algorithm, which attempts to minimize zigzags and crisscrosses on the timing-critical paths of a circuit. We observed th...

Fractional Cut: Improved Recursive Bisection Placement
In this paper, we present improvements to recursive bisection based placement. In contrast to prior work, our horizontal cut lines are not restricted to row boundaries; this avoid...
