Behavioural macromodelling for analogue fault simulation
Mark Zwoliński · 1995
This paper describes the modelling of bridging defects in analogue circuits as changes to the external, observable characteristics of the circuits. By considering the behaviour of operational amplifier circuits configured to perform particular circuit functions, the varieties of faulty operation are reduced in number and the defective behaviours can be grouped together. This can reduce the overall number of faults to be simulated by 50%. As we are modelling the functional behaviour of circuit blocks, we need to generate macromodels of those blocks. Of particular interest to us has been the modelling of the supply current. (6 pages)
