(2) March X
The March X algorithm is a simpler and therefore faster algorithm, but not as thorough as it consists of only four March
elements with a total of four operations
1. Stuck At Faults (SAF)
2. Transition Faults (TF)
3. Inversion Coupling Faults (Cfin)
4. Address Decoder Faults (AF)
These are the 4 March elements:-
1. Write all zeros to array ( <>(w0) )
2. Starting at lowest address, read zeros, write ones, increment up array bit by bit. ( >(r0,w1) )
3. Starting at highest address, read ones, write zeros, decrement down array bit by bit. ( <(r1,w0) )
4. Read all zeros from array. ( <>(r0) )
