摘要
VLSI布局问题是集成电路物理设计过程中的关键步骤,它直接影响整个设计的成败。Slicing结构是一种简单而高效的布局表示方法,采用正则波兰表达式编码,将模拟退火与禁忌搜索算法结合形成了一种以模拟退火算法为基础的混合算法进行求解,用MCNCbenchmarks进行实验,结果表明:文章提出的混合算法比模拟退火算法在求解效率和质量上都有较大的提高。
BBL placement is one of the most important steps in VLSI circuit layout. Slicing is a kind of representation, which is simply and effective. The normalized Polish expression is employed to code. A hybrid algorithm combined simulated annealing and tabu search is presented to solve the BBL placement. The experimental results using MCNC benchmarks show that our approach is prior to that of simulated annealing.
