To run PDN IR drop analysis, you build a powerDistributionNetwork model per power net, assign topology via setNetworkParameters, configure setDCParameters and setDCRules, then invoke voltage(PDN) and current(PDN) to compute DC distribution and report violations.

Power net discovery uses cadnetList-based net enumeration and classifies power or ground nets by naming conventions. Nominal rail voltage is inferred through regex-based parsing from net names, with isnan handling to skip rails that have incomplete voltage information.

PDN topology assignment requires a Sense node, but you can use a resistor fallback when a test point is unavailable. You configure this through setNetworkParameters, designating inductors as sources and ICs as loads before running DC analysis.

Yes, batch rail workflows apply the same DC analysis process to multiple power and ground rails on the same board. The workflow identifies rails by naming conventions and skips any rails with incomplete information during multi-net evaluation.

Design rule evaluation checks voltage limits and current density constraints, including via current constraints. You define these rules using setDCRules before executing voltage and current distribution checks on the power distribution network.

This approach focuses strictly on PDN DC analysis to avoid mixing concerns. You should steer PCB imports, EM analysis, stackup or material setup, and transmission-line work to dedicated skills to maintain toolchain boundaries.
