Given the significance of placement in IC physical design, extensive research studies
performed over the last 50 years addressed numerous aspects of global and detailed …

Placement is critical to the timing closure of the very-large-scale integrated (VLSI) circuit
design flow. This paper proposes a differentiable-timing-driven global placement framework …

Timing optimization is critical to integrated circuit (IC) design closure. Existing global
placement algorithms mostly focus on wirelength optimization without considering timing. In …

This paper proposes an efficient algorithm to synthesize prefix graph structures that yield
adders with the best performance-area trade-off. For designing a parallel prefix adder of a …

Optimizing timing is critical to the design closure of integrated circuits (ICs). However, most
existing algorithms for circuit placement focus on the optimization of wirelength instead of …

This chapter reviews two basic sets of netweighting algorithms: static netweighting and
dynamic netweighting. It explores two global placement approaches: partitioning and force …

Placement is one of the most important steps in the RTL-to-GDSII synthesis process, as it
directly defines the interconnects, which have become the bottleneck in circuit and system …

The traditional purpose of physical synthesis is to perform timing closure, ie, to create a
placed design that meets its timing specifications while also satisfying electrical, routability …

Placement migration is the movement of cells within an existing placement to address a
variety of post-placement design closure issues, such as timing, routing congestion, signal …

(57) ABSTRACT A method of detailed placement for ICs is provided. The method receives
an initial placement and iteratively builds sets of constraints for placement of different groups …
