ES2E3-15 Digital Systems Design
To introduce students to the principles and practice of designing digital electronic circuits, with a focus on field programmable gate array implementation, including the tool flow, architecture, testing, and design for performance.
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
Recap of combinational and sequential circuits: gates, multiplexers, encoders, decoders, latches, D flip-flop, registers, shift registers.
Design with hardware description languages: (Verilog) module definitions, gate-level circuits, assign statements, behavioural combinational descriptions, behavioural synchronous descriptions.
Design flow and FPGA architecture: basic circuit synthesis, FPGA logic blocks, hard blocks, I/O, mapping to FPGA blocks, placement and routing, configuring FPGAs.
Testing digital circuits: basic Verilog testbenches, self-checking testbenches, file I/O for input/output vectors, testing strategies.
Arithmetic circuits: limits of ripple adders, carry-lookahead adders, multipliers, fixed-point data representation and resulting errors, floating point circuit complexity.
Timing and pipelining: basic combinational timing characteristics, timing of synchronous components, computing circuit timing performance, pipelining for improved performance, hazards, race conditions, and metastability.
Processors and I/O: basic structure of a processor and how this relates to performance, integrating peripherals over UART, SPI, I2C, and faster serial standards, computing data rates for these standards.
By the end of the module, students should be able to:
- Understand the theory of combinational and sequential circuits and how these combine in the design of digital computing circuits through the use of the Verilog hardware description language (HDL).
- Assess the digital design flow as currently practised professionally in industry, with reference to field programmable gate arrays, and at a more general level, to custom application specific integrated circuits.
- Examine how mathematics is performed in custom circuits, and how simple units can be combined to implement compute datapaths.
- Develop a testing strategy and design a testbench to evaluate the functional correctness of a circuit using the testing features of the Verilog HDL and a professional standard simulator.
- Discuss the performance of synchronous digital circuits, based on the timing of basic components, and how pipelining affects performance, and how this differs from measuring the performance of software running on processors.
