Study Notes

Introduction to HDL Programming

A Hardware Description Language (HDL) is a set of notations used for modeling the logical function of digital circuits and systems.
HDLs allow users to describe a circuit using words and symbols, which can then be converted into configuration data loaded into Programmable Logic Devices (PLDs).

Programmable Logic Devices (PLDs)

A Field-Programmable Gate Array (FPGA) is an integrated circuit designed to be configured by a customer or designer after manufacturing.
An FPGA consists of:
- IOB (Input/Output Block): Programmable pins
- CLB (Configuration Logic Block): Programmable Gates

HDL Code vs. Software Programming Languages

HDLs resemble high-level programming languages such as C or Python.
HDL code involves parallel operation, whereas programming languages represent sequential operation.
In HDL code, separate portions of the digital hardware can operate simultaneously, although the corresponding lines of code are written using a top-to-bottom organization.

Example of HDL Code

An example of HDL code includes:
- Entity declaration (e.g., entity Circuit_1 is)
- Port declaration (e.g., Port (a : in STD_LOGIC; b : in STD_LOGIC; out1 : out STD_LOGIC);)
- Architecture declaration (e.g., architecture Behavioral of Circuit_1 is)
- Signal assignment (e.g., out1 <= ...;)

Test your knowledge on Hardware Description Language (HDL) programming, used for modeling digital circuits and systems. Learn about how HDLs allow circuit descriptions to be converted into configuration data for Programmable Logic Devices (PLDs) like FPGAs.
