Na era dos nanômetros, o problema de integridade de energia tornou-se uma das questões críticas. Embora a verificação antecipada deste problema possa acelerar a análise, não há tantas ferramentas disponíveis atualmente devido às informações limitadas de projeto em níveis elevados. A maioria das abordagens existentes no nível do portão requerem informações extras da biblioteca de células, o que pode exigir esforços extras de caracterização durante a migração para novas bibliotecas de células. Portanto, uma abordagem analítica é proposta neste artigo para estimar dinamicamente as formas de onda da corrente de alimentação no nível da porta usando apenas informações da biblioteca existente, mesmo para circuitos sequenciais. Os resultados experimentais mostraram que os erros de estimativa de uma abordagem tão rápida são de apenas 10% em comparação com os resultados do HSPICE.

Abstract: In the nanometer era, the power integrity problem has become one of the critical issues. Although checking this problem earlier can speed up the analysis, not so many tools are available now due to the limited design information at high levels. Most existing approaches at gate level require extra information of the cell library, which may require extra characterization efforts while migrating to new cell libraries. Therefore, an analytical approach is proposed in this paper to dynamically estimate the supply current waveforms at gate level using existing library information only, even for sequential circuits. The experimental results have shown that the estimation errors of such a quick approach are only 10% compared to HSPICE results.
