# PB170 Course intro

---

## Course goals
- gain insight into basic digital logic building blocks
- practice theoretical knowledge from PV170 course
- learn to read datasheets/find info about components
- the course will not be as fleshed out as some big courses

---

## Course plan
- closely follows PV170
- preliminary schedule:
    - 19.9  / 22.9 - Course intro, digital logic electronics
    - 26.9  / 29.9 - numerical systems, formats, operations
    - 3.10  / 6.10 - combinational circuits
    - 10.10 / 13.10 - arithmetic circuits
    - 17.10 / 20.10 - hazards in circuits
    - 24.10 / 27.10 - advanced combinational circuits
    - 31.10 / 3.11 - sequential circuits I
    - 7.11  / 10.11 - sequential circuits II
    - 14.11 / 17.11 - no seminar
    - 21.11 / 24.11 - counters, registers etc.
    - 28.11 / 1.12 - intro to verilog/FPGA
    - 5.12  / 8.12 - continuation of verilog/FPGA
    - 12.12 / 15.12 - project consultations

---

## Grading
- mandatory attendance (2 unexcused absences max)
- mandatory homework (graded OK/NOK)
    - expect two or three homeworks
    - deadline will be until next seminar
- final project (either verilog on FPGA/simulated or built on breadboard)
    - should be sufficiently advanced
    - the project will be defended/presented during exam period

---

## Study materials
- some short slides (like these) will be in study materials
- info and extra materials  will also be in interactive syllabus in IS

---

## Tools that we will use
- Digital (https://github.com/hneemann/Digital)
- Falstad (https://www.falstad.com/circuit/circuitjs.html)
- Hardware available in this lab
    - components, breadboards, power supplies
- later Quartus Prime and verilog sim tools

---

# 01 - Electronics
- digital circuits are just analog circuits with few simplifications
- Ohm's law will be sufficient for us
    - I = U/R
- Falstad for simulation
---

## Basic parts
- passives
    - resistors
    - capacitors
    - inductors
- semiconductors
    - transistors
    - diodes
- electromechanical
    - switches
    - buttons
---

## connecting some parts
- light up an LED
- light it up through a button

- we need some info about the parts first
- and also the tools we are going to use

---

## Transistors
- transistor ~= switch (very simplified)
- connecting a transistor

---

## RTL logic
- most basic logic

- constructing some logic gates

---

## TTL logic
- enhances on RTL
- no more resistors which burn power
- not easy to build on breadboard

---

## CMOS logic
- uses complementary MOSFETs
- nowadays most common one (bleeding edge is on FinFETs)
