模拟电路的自动化设计在提高设计效率和缩短产品上市时间方面有着广阔的应用前景,但也面临着设计复杂性的瓶颈。提出了一种基于仿真的模拟电路综合优化方法--智能多起点法。所提出的智能MSP是基于MSP优化的框架,这被证明是更有效的比其他全局优化方法,如模拟退火,遗传算法,粒子群优化等。有效的技术,包括有偏见的起点选择,稀疏回归和概率TABU是在智能-MSP和使算法相当聪明的方式,整体优化过程是自适应的,从以前的局部搜索学习,可以有效地产生最优结果,以接近全局最优。实验结果表明,该方法比原MSP方法快<inline-formula><tex-math notation="LaTeX">2.6-12.5\times $</tex-math></inline-formula>,比其他方法快<inline-formula><tex-math notation="LaTeX">1.3-2100\times $</tex-math></inline-formula>。
Automated analog circuit design is promising for increasing the design productivity and narrowing the time-to-market, but is facing the bottleneck of tremendous design complexity. In this paper, a simulation-based optimization approach named smart-multiple starting point (MSP) is proposed for analog circuit synthesis. The proposed smart-MSP is based on the framework of MSP optimization, which is shown to be much more efficient than other global optimization methods like simulated annealing, genetic algorithm, particle swarm optimization, etc. Efficient techniques including heuristic-biased starting point selection, sparse regression and probabilistic TABU are developed in smart-MSP and make the algorithm quite smart in a way that the overall optimization process is self-adaptive by learning from the previous local searches and can efficiently produce optimal results to approximate the global optimum. Experiments have demonstrated that the proposed smart-MSP is <inline-formula> <tex-math notation="LaTeX">${2.6-12.5\times }$ </tex-math></inline-formula> faster than the original MSP method, and is <inline-formula> <tex-math notation="LaTeX">$ {1.3-2100\times }$ </tex-math></inline-formula> faster than other state-of-the-art methods.
