1. A computer implemented method of checking electronic circuit netlists for compliance to at least one design rule, said method comprising: providing a computer non-transitory readable netlist of an integrated circuit to be tested, said netlist comprising a plurality of subgraphs and candidate circuit elements; defining a template for at least one design rule, said at least one design rule comprising a candidate identifier portion and a design rule compliance portion; wherein said candidate identifier portion of said design rule comprises at least one wildcard or at least one ranged attribute; wherein said design rule compliance portion of said design rule further comprises rules to determine components or connections that are missing from said first set of target subgraphs; using said candidate identifier portion of said at least one design rule to define at least one subgraph and/or candidate circuit element to be tested, wherein said at least one subgraph or candidate circuit element to be tested are defined by either their net name pattern, connected device name pattern, arrangement of circuit components, or block of Boolean logic candidate selection rules; wherein said net name pattern, connected device name pattern, arrangement of circuit elements, or block of Boolean logic candidate selection rules comprises at least one wildcard or at least one ranged attribute; further using the graphical user interface of a computer to input a graphical pattern comprising a collection of one or more electronic devices and/or building blocks to at least partially define said candidate identifier portion of said at least one design rule; wherein said building blocks comprise at least one building block selected from the group consisting of IO pad definition, IO directionality definition, Primary high clamps, Primary low clamps, series resistance in signal clamps, secondary high clamps, and secondary low clamps; using a computer processor, said definition of at least one subgraph or candidate circuit element, said netlist, and said candidate identifier portion of said at least one design rule to perform a first search broadly identifying a first set of target candidate subgraphs; and using a computer processor, said first set of target subgraphs and the design rule compliance portion of said at least one design rule to identify compliance of said first set of target subgraphs to the design rule compliance portion of said at least one design rule, thereby identifying design rule noncompliant subgraphs; and either reporting or storing in memory said first set of target subgraphs and said design rule noncompliant subgraphs; and wherein for at least some of said design rule noncompliant subgraphs, further reporting at least one of type of violation, number of similar violations, severity of violation, device name, circuit subgroup, or placement in the circuit.
