A new fast timing-driven placement is presented in this paper, which is partitioning-based method, explicitly considering the congestion for island style FPGAs. The most distinct feature of this approach is that it not only reduces the circuit critical path delay efficiently, but also takes congestion into account. The harmony between partitioning objective and timing improvement goal is kept; moreover,...
Usage of multiple supply voltages has raised new design challenges in IC design. We focus on the problem of power aware placement when dual supply voltages provide two high performance and low power working modes on each FPGA tile. To meet timing constrains, all logic elements within a tile need to work in the high performance mode when at least one element within that tile has tight timing requirements...
Asynchronous design has become more and more popularin last years. Many tools and design methodologies have been developed for this kind of circuits. Unfortunately only few of them are focused on their implementation onto FPGAs. Nowadays FPGAs are widespread in many applications and they have enough complexity to allow prototyping also complex designs. For this reason this paper is focused on the...
In this paper we explore microprocessor performance models implemented on FPGAs. While FPGAs can help with simulation speed, the increased implementation complexity can degrade model development time. We assess whether a simulator split into closely-coupled timing and functional partitions can address this by easing the development of timing models while retaining fine-grained parallelism. We give...
