摘要:
A method of testing for shorts between nodes of a circuit assembly includes parsing circuit design data to identify positional data for nodes of a circuit assembly, and using the positional data to classify ones of the nodes as members of a supernode, where each member of the supernode is unlikely to be shorted to any other member of the supernode. Tests for shorts in a set of nodes that includes the supernode and a plurality of other nodes of the circuit assembly are then conducted, by iteratively i) stimulating a particular one of the set of nodes, and ii) while stimulating the particular node, grounding at least one other node in the set of nodes and monitoring a current flow through the particular node. When stimulating or grounding a supernode, all of the nodes that are members of the supernode are stimulated or grounded. If a current flow is detected through one of the stimulated nodes, the circuit assembly is indicated to be defective. Other embodiments are also disclosed.

The present invention is directed to contryphan peptides having 6-12 amino acids, preferably including one or more D-tryptophan or D-leucine residues. The peptides of the present invention are generically termed "contryphans," although the D-leucine containing contryphans are sometimes referred to as leu-contryphans. More specifically, the present invention is directed to contryphan peptides having the general formula Xaa.sub.1 -Cys-Xaa.sub.2 -Xaa.sub.3 -Xaa.sub.4 -Pro-Xaa.sub.5 -Cys (SEQ ID NO:1), wherein Xaa.sub.1, is any amino acid or des-Xaa.sub.1, Xaa.sub.2 is Pro, 4-trans-hydroxyproline or Val, Xaa.sub.3 is D-Trp, L-Trp, D-Leu or L-Leu, preferably D-Trp or D-Leu, Xaa.sub.4 is any amino acid and Xaa.sub.5 is Trp or Tyr. When the peptide contains Xaa.sub.1, it is preferably Gly, Glu, or Lys, most preferably Gly. When Xaa.sub.3 is D- or L-Trp, Xaa.sub.2 is preferably Pro or 4-trans-hydroxyproline. When Xaa.sub.3 is D- or L-Leu, Xaa.sub.2 is preferably Val. The carboxy terminus may contain a carboxyl or an amide, preferably an amide. The present invention is further directed to the specific contryphan peptides and propeptides as described herein. The present invention is also directed to nucleic acids encoding the contryphan peptides and their propeptides as described herein. The contryphans of the present invention are useful as anticonvulsant or neuroprotective agents.
