Capo: Congestion-Driven Placement for Standard-cell and RTL Netlists with Incremental Capability
نویسندگان
چکیده
In this chapter, we describe the robust and scalable academic placement tool Capo. Capo uses the min-cut placement paradigm and performs (i) scalable multi-way partitioning , (ii) routable standard-cell placement, (iii) integrated mixed-size placement, (iv) wirelength-driven fixed-outline floorplanning as well as (v) incremental placement.

A Standard-Cell Placement Tool for Designs with High Row Utilization
In this paper we study the correlation between wirelength and routability for standard-cell placement problem, under the fixed-die place-androute environment. We present a placement tool with better routability for designs with high row utilization. Compared to a well-known industrial placement tool, our placer produces placements with equal or better routability, 13.2% better half-perimeter wi...
متن کاملAn Optimized Design Flow for Fast FPGA-Based Rapid Prototyping
In this paper, we present an optimized design flow to map Register-Transfer-Level (RTL) netlists onto multiple-FPGA architectures. Our FPGA-dedicated method fully exploits design structure by letting the basic design steps technology mapping, hierarchical partitioning, floorplanning and signal flow driven placement, interact. This efficiently reduces runtime and yields design implementations of...
متن کاملCongestion Driven ' Placement for ' VLSI Standard Cell Design
The submicron regime has caused the interconnect delay to become a critical determiner of circuit performance. As a result, circuit placement is starting to play an important role in today's high performance chip designs. In addition to wirelength optimization, the issue of reducing excessive congestion in local regions such that the router can finish the routing successfully is becoming anothe...
متن کاملPractical Experiences with Standard-Cell Based Datapath Design Tools
Commercial tools for standard-cell based datapath design are here classed according to design flows, and the advantages of each class are discussed with the results of two test circuits. Algorithmic generation of netlists and of relative cell placement can help reducing area but, contrary to common belief, appears often detrimental to speed. Extraction of regularity from synthesized netlists is...

Force-directed placers are an attractive approach for placement and are of interest for several reasons. Large standard cell and mixed-size problems are handled seemlessly by such methods. Furthermore, force-directed placers provide continuous trajectories for cell locations and therefore seem quite amenable to timingand congestion-driven placement, physical re-synthesis, and so forth. Unfortun...
