A method and system is provided for automatically generating valid at speed structural test (ASST) test groups. The method includes loading a netlist for an integrated circuit into a processor. The method further includes determining a plurality of clock domain crossings between a plurality of clock domains within the integrated circuit. The method further includes generating a first test group. The method further includes adding a first clock domain of the plurality of clock domains to the first test group. The method further includes adding a second clock domain of the plurality of clock domains to the first test group when the second clock domain does not have a clock domain crossing into the first clock domain.

Automatic generation of valid at-speed structural test (ASST) test groups

A system and method that controls the start time of different clocks in different clock domains, each of which is controlling an I/O, provides that the first cycle of each time domain is within a predetermined timing delay of one another. Reset signals are pipelined across the clock domains such that all the clocks trigger at substantially the same time. The clock channels may be arranged logically and physically in n groups of m channels with delays associated with each n group according to the relative position of the n group within the sequence of the n groups.
