Question

Which model cannot simulate directly?

(a) circuit level model

(b) switch-level model

(c) gate level model

(d) layout model

I have been asked this question during an interview.

The above asked question is from Levels of Hardware Modelling topic in chapter Specification of Embedded Systems

Answer 1

Correct answer is (d) layout model

For explanation: The layout model reflects the actual circuit model and this includes the geometric information and this model cannot be simulated directly because it does not provide the information regarding the behavior.
