Definitions

  • FIG. 3A there is shown a schematic circuit 56, which is closely similar to the circuit 40 (FIG. 2A) .
  • the circuit 56 however has an upper wire 58 reconfigured from the wire 50 (FIG. 2A) to lower the parasitic resistance of the wire 50 by making the wire 58 substantially wider.
  • the parasitic capacitance here between the wires 46 and 58 is substantially higher than the parasitic capacitance between the wires 46 and 50 as indicated by the small circle 52 in FIG. 2A.

Abstract

Procédé servant à améliorer la conception, l'implantation et la capacité d'un circuit intégré à très grande échelle (VLSI) possédant une pluralité de blocs et comportant des éléments parasites, ce qui consiste initialement à concevoir chacun des blocs de façon séparée et parallèle, à simuler chaque conception de bloc et à extraire des éléments parasites identifiés dans chaque bloc, puis à mémoriser les informations obtenues dans une base de données commune à la totalité des blocs. Ce procédé consiste, de plus, à reporter la notation des extractions parasites sur une base continue pour chacun des blocs afin de tirer avantage de la conception initiale, de la simulation et des étapes suivantes, à élaborer une implantation comportant des extractions parasites pour chaque conception de bloc après la simulation réussie de ce dernier, à réaliser une implantation totale de puce avec extraction parasite et à simuler au moyen de l'annotation des éléments parasites, l'implantation totale de la puce afin d'en optimiser la conception.
