The application discloses a circuit netlist intelligent correction method and system based on a three-layer verification mechanism. The method constructs a progressive architecture through a syntax verification layer, a PDK compliance verification layer and a circuit integrity verification layer, comprehensively detects the SPICE circuit netlist, the circuit integrity verification layer analyzes the signal flow direction and polarity from input to output based on a graph structure, and performs contrast detection in combination with basic circuit unit templates such as differential pairs and current mirrors, and an intelligent decision engine performs hierarchical processing according to error types: format pairing abnormalities are directly corrected, parameter boundaries or polarity adjustments generate correction suggestions for confirmation, and topological defects of missing basic units or signal transmission path breaks are fed back to an AI engine for regeneration, and after correction, the correctness is ensured through closed-loop re-verification, and the efficiency and accuracy of netlist verification are significantly improved.
