Intermodule test across system bus utilizing serial test bus

摘要: Intermodule testing in a computer system including plurality of modules interconnected via bus is performed by means serial test which incorporated into the for components, example integrated circuits, used to construct system. data maintained memory on each and accessible through operations bus. retrieved set up so that one module drives with signals defined vectors included within intermodule data. The remaining are receive signals. Tables developed accordance define drive leads also receiving received sampled compared what should have been detect errors communications. selection rotated until all driven
