IE1204 Digital Design 7.5 credits

In this course we learn to build combinatorial and sequential digital circuits, which form the basis for building computers in later courses. We learn to both analyze and design with basic building blocks such as OR, NOR, AND, NAND and different flip-flops, and test our circuits in computer simulations and in practical connections.

- draw and interpret schematics with symbols for logic gates and standard digital components

- analyse small combinational and sequential logic circuits and determine their functionality

- design small combinational and sequential logic circuits which implement a given function

- implement small combinational and sequential logic circuits with standard components and be able to find wrong connections

- use tools for simulation of combinational and sequential digital circuits

- determine the functionality of small digital circuits that are described using a hardware description language

- give the functionality of simple CMOS-schematics by a boolean equation

- understand how the physical properties affect the timing characteristics of digital circuits

Examination and completion

If the course is discontinued, students may request to be examined during the following two academic years.

Grading scale

A, B, C, D, E, FX, F


  • LABA - Laboratory Work, 3.5 credits, grading scale: P, F
  • TENA - Examination, 4.0 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.


Other requirements for final grade

For the final grade all examination parts (exam and laboratory course) have to be passed.

Opportunity to complete the requirements via supplementary examination

Ethical approach

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
