Abstract :
In this paper, we present a methodology to perform fast testing of the control path of self-timed circuits. The speedup is achieved by testing all the execution paths in the control simultaneously. The circuits considered in this paper are those designed using an OCCAM based circuit compiler (1991). This Compiler translates an OCCAM program description into an interconnection of pre-existing self-timed macro-modules (1989, 1991). The method proposed involves modifying certain modules and structures in such a way that the circuits obtained by translation using these modified modules are testable in above mentioned way
