Unformatted text preview: performed on all 32 bits at once. There are two ways to realize bitwise parallelism in fault simulation: parallelism in faults and parallelism in patterns. These two approaches are referred to as parallel fault simulation and parallel pattern fault simulation . 3.4.2.1 Parallel Fault Simulation Parallel fault simulation was proposed as early as the 1960s [Seshu 1965]. Assuming that binary logic is utilized, one bit is sufficient to store the logic value of a signal....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
