Abstract
According to one aspect of the present disclosure, a method and technique for identifying odd nets in a hierarchical electronic circuit design is disclosed. The method includes: receiving a very high-speed integrated circuit hardware description language (VHDL) model of an electronic circuit design; modifying an architecture section of VHDL code of each endpoint component of the VHDL model to connect each input/output (IO) of the endpoint component VHDL code to an instance of a snoop VHDL code; executing a simulation of the VHDL model through a plurality of clock cycles while driving a logical value by the snoop VHDL code and deriving simulation clashes detected by the snoop VHDL code for each IO of the endpoint components; and extracting an odd net topology for the VHDL model based on the simulation clashes derived from the simulation.
