We therefore present a timing driven N-way partitioning algorithm based on simulated annealing for technology-mapped FPGA circuits. The signal path delays are estimated during partitioning using a timing model specific to a multiple FPGA architecture. The model combines all possible delay factors in a...
The work of present timing-driven routing algorithms mainly is partitioned into three aspects: the delay model, the objective formulation and the solution space. 现有时延驱动布线算法的工作主要分为三个方面:时延模型、目标形式化、解空间。 2. The experiment results show that this is an efficient meth...

A new timing driven placement algorithm based on two equal terminals partition method for standard cell placement was presented. It pays much attention to critical path topologies and transforms the optimization for path delay into cell location optimization. A tracelist determining the order of cell ...

In this section, we describe our seed-based routability and timing-driven nonuniform depopulation clustering technique, T-NDPack. We present the pseudocode and notable implementation insights. 3.1. Algorithm Flow T-NDPack chooses the seed block based on criticality first. The first block that is ...
We evaluate two variants of constraints used: In the variant with fine grained constraints, all individual atomic nets have their delay constrained using the set_max_delay timing exception, ensuring that the design still meets timing constraints and forcing the timing driven optimization to operate. ...
In static (table-driven) scheduling, the order of process execution is determined at design time. It has been used for periodic process scheduling, where a static schedule exists for the least common multiple (LCM) of all process periods.29 The process sequence can be stored in a schedule ta...
