Programmable and Logic Devices
FEKT-GPLDAcad. year: 2019/2020
Students get more detailed knowledge in the area of digital circuits design, especially with respect to their implementation into PLDs (FPGAs, CPLDs) and ASICs. Students get overview of current technology of these integrated circuits, their off-the-shelf architectures, principles of design and application of basic digital subsystems (counters, finite state machines, memory structures). During the PC lectures students get familiar with modern system for FPGA configuration. This includes description of the digital system (using VHDL source codes, schematic, IP cores), its implementation and verification using simulator. After passing the course students are able to design and implement simple digital system into an FPGA (using VHDL language).
Learning outcomes of the course unit
The graduate is able to: (1) describe simple digital system using VHDL, (2) verify simple digital system using VHDL, (3) choose type of finite state machine and give reasons for the choice, (4) design and implement a finite state machine using VHDL, (5) compare different architectures of PLDs and choose a proper one for particular application, (6) specify timing requirements for a design and verify that they are met after implementation, (7) implement simple IP cores like memories and simple DSP blocks (FIR filtres), (8) implement simple microcontroller into FPGA, program it and use in target application, (9) state requirements on FPGA power supply system, (10) analyze and prevent/solve basic signal integrity issues.
Students are expected to know basic of impulse and digital technology: the Boolean algebra, Karnaugh maps, truth tables, function of basic gates and flip-flops (registers), principle and effect of signal propagation through active and passive transmission elements.

Planned learning activities and teaching methods
Techning methods include lectures and computer laboratories. Course is taking advantage of e-learning (Moodle) system. The main focus is on computer laboratories with strong emphasis on practical skills.
Assesment methods and criteria linked to learning outcomes
Students obtain points for the activity in computer labs during the semester. The final exam is composed of written, practical and oral part. The exam will be in a remote form.
