▪ Simulate a basic VHDL design
▪ Write a VHDL testbench and identify simulation-only constructs
▪ Identify and implement coding best practices
▪ Optimize VHDL code to target specific silicon resources within the Xilinx FPGA
▪ Create and manage designs within the Vivado Design Suite environment

Course Outline 2021.1

Day 1

Introduction to VHDL
Discusses the history of the VHDL language and provides an overview of the different features of VHDL. {Lecture}
▪ VHDL Design Units
Provides an overview of typical VHDL code, covering design units such as libraries, packages, entities, architectures, and configuration. {Lecture, Lab}
▪ VHDL Objects, Keywords, Identifiers
Discusses the data objects that are available in the VHDL language as well as keywords and identifiers. {Lecture}
▪ Scalar Data Types
Covers both intrinsic and commonly used data types. {Lecture}
▪ Composite Data Types
Covers composite data types (arrays and records). {Lecture}
▪ VHDL Operators
Reviews all VHDL operator types. {Lecture}
▪ Concurrency in VHDL
Describes concurrent statements and how signals help in achieving concurrency. {Lecture}
▪ Concurrent Assignments
Covers both conditional and unconditional assignments. {Lecture, Lab}
▪ Processes and Variables
Introduces sequential programming techniques for a concurrent language. Variables are also discussed. {Lecture, Demo, Lab}

Day 2

Conditional Statements in VHDL: if/else, case
Describes conditional statements such as if/else and case statements. {Lecture, Lab}
▪ Sequential Looping Statements
Introduces the concept of looping in both the simulation and synthesis environments. {Lecture, Lab}
▪ Delays in VHDL: Wait Statements
Covers the wait statement and how it controls the execution of the process statement. {Lecture}
▪ Introduction to the VHDL Testbench
Introduces the concept of the VHDL testbench to verify the functionality of a design. {Lecture, Lab}
▪ VHDL Assert Statements
Describes the concept of VHDL assertions. {Lecture}
▪ VHDL Attributes
Describes attributes, both predefined and user defined. {Lecture}
▪ VHDL Subprograms
Covers the use of subprograms in verification and RTL code to model functional blocks. {Lecture}
▪ VHDL Functions
Describes functions, which are integral to reusable and maintainable code. {Lecture, Lab}
▪ VHDL Procedures
Describes procedures, common constructs that are also important for reusing and maintaining code. {Lecture}

Day 3

▪ VHDL Libraries and Packages
Demonstrates how libraries and packages are declared and used. {Lecture, Lab}
▪ Interacting with the Simulation
Describes how to interact with a simulation via text I/O. {Lecture}
▪ Finite State Machine Overview
Provides an overview of finite state machines, one of the more commonly used circuits. {Lecture}
▪ Mealy Finite State Machine
Describes how to implement a Mealy state machine in which the output is dependent on both the current state and the inputs. {Lecture}
▪ Moore Finite State Machine
Demonstrates how to implement a Moore state machine in which the output is dependent on the current state only. {Lecture, Lab}
▪ FSM Coding Guidelines
Describes the guidelines and recommendations for using one or more procedural blocks when coding a finite state machine. {Lecture}
▪ Vivado Simulator and Race Conditions in VHDL
Introduces the Vivado simulator simulation environment. Race conditions are also discussed. {Lecture}
▪ Writing a Good Testbench
Explores how time-agnostic, self-checking testbenches can be written and applied. {Lecture, Lab}
▪ Targeting Xilinx FPGAs
Focuses on Xilinx-specific implementation and chip-level optimization. {Lecture, Lab}
