LabVIEW Design of
Digital Integrated Circuits
FPGA IC Implantation
A Simple Way to Build an IC
• Modern digital electronics uses an EDA
software tools to design the block diagram of
the circuit which is then downloaded into a
programmable chip.
• The resulting chip becomes an integrated
circuit which will work exactly as it is
designed.
How Does An FPGA Work?
• A field-programmable gate array (FPGA) is
a
semiconductor
device
containing
programmable
logic
blocks,
and
programmable interconnects.
• Logic blocks can be programmed to perform
the function of basic logic gates such as
AND, and XOR, or more complex
combinational functions such as decoders or
simple mathematical functions.
• In most FPGAs, the logic blocks also include
memory elements, which may be simple flipflops or more complete blocks of memory.
• A hierarchy of programmable interconnects
allows logic blocks to be interconnected as
needed by the system designer, like a onechip programmable breadboard. Logic
blocks
and
interconnects
can
be
programmed by the designer. After the
designer download his designing patterns
into the FPGA chip, one gets his own IC.

Requirement of this Lab
• Build a 3-8 Decoder with LabVIEW
• Your design does need to be professional.
• Make sure your design is functional.
