21. An article of manufacture comprising a non-transitory computer accessible storage medium having stored thereupon a sequence of instructions which, when executed by at least one customizable processor executing one or more threads, causes the at least one customizable processor to perform a set of acts for checking or verifying shapes in an electronic design, the set of acts comprising: using a computer system to execute a process, the process comprising: identifying or determining a dictionary for an electronic design; reducing, at a sliced line module stored at least partially in memory and including or function in conjunction with one or more microprocessors of the computer system, dimensionality of design data in a region at least by identifying or determining a first sliced line for the region in the electronic design, wherein the first sliced line includes one or more projected boundaries of the region; and checking or verifying the electronic design to flag one or more non-conforming shapes by using at least the first sliced line.
