Question

How many categories are there for the low-level simulation?

(a) 2

(b) 3

(c) 4

(d) 5

This question was posed to me in an internship interview.

The origin of the question is Debugging Techniques in section Emulation and Debugging Techniques of Embedded Systems

Answer 1

The correct answer is (a) 2

Best explanation: There are two categories for the low-level simulation. The first category simulates the memory system, programming model and can offer simple debugging tools whereas the second category simulation provides timing information based on the number of clocks.
