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.

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 - Written Exam, 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.

Opportunity to complete the requirements via supplementary examination

There is the possibility of completion.

Opportunity to raise an approved grade via renewed examination

Raising a grade is allowed.


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.
