摘要：An integrated circuit having a built-in self test facility, the integrated circuitbeing partitioned into a number of sub-circuits each of which comprises a combinatoriallogic circuit (CLB) and a register (RB). The sub-circuits are coupled together so that each

combinatorial logic circuit (CLB) has its inputs coupled to at least one register (RB), has itsoutputs coupled to at least one register (RB), and the output of the overall integratedcircuit is taken from one or more registers (RB). Each register (RB) has its functional modecontrolled by predetermined signals to an associated local decoder, the functionalmodes of the registers (RB) being selected to initiate a test operation for the testing ofthe integrated circuit.
