Self Contained Test for Digital Avionics. Designers Guide,
Abstract
The complexity of VLSI circuits considered for use in future avionics modules makes testing of these modules virtually impossible unless provisions for test are incorporated from the very beginning of design. The circuit complexity and packaging density of VLSI will make designing for testability an important requirement. With the development of a testable design, the equipment can then be maintained in a cost effective manner utilizing Self-Contained-Test(SCT) techniques. The most direct method of providing complete fault isolation in a digital system is to employ Self-Contained-Test hardware on each replaceable unit (module). This approach is practical if the SCT hardware remains in a small percentage of the total cost of the replaceable unit and requires negligible cooling and power. Systems using VLSI technology can meet the requirements as mentioned above. (Author)
