Abstract- Advancement in computer system hardware makes it
difficult to meet the demands of teaching computer architecture
and organization. Visualization of different architectures
enhances the learning process among students by using
simulators. This paper attempts to give a survey on the following
simulators
(1) Electrical Numerical Integrator and Computer
(ENIAC) was the first electronic digital universal computer built
at Pennsylvania University in 1944-1946.,
(2) The Visible VirtualMachine (VVM) based on Little Man Computer (LMC) which is
general for von Newmann computer architecture,
(3) MARS anEducation-Oriented MIPS Assembly Language Simulator,
(4)Logisim for simulating digital logic circuits and
(5) SPIM forMIPS Assembly Language Simulator that are going to be taughtin the course Computer Architecture and Organization by the
faculty members. Also, evaluate the selected simulators according
to the criteria established in the course meetings.
