Logical Circuits

The course is a substitute for:

Logical Circuits (X36LOB)

Lecturer:

Neurčen (gar.)

Tutor:

Neurčen (gar.)

Supervisor:

Department of Computer Science and Engineering

Synopsis:

The students get acquaintance with design of combinatorial and sequential circuits, namely those used in digital computers from gate level to MSI and LSI. Analysis and basic testing methods are included. Laboratory part allows the student to relate the learned concepts with practical design in a real working environment (XILINX EDA tools, LABORO).

Requirements:

Active participation in lab courses is necessary. Requirements for the assessment: elaborating a semester work and getting the necessary number of points.

Requirements for the exam: getting the assessment and the necessary number of points.
