Glossary of Terms
ABEL – Advanced Boolean Expression Language, low-level language for design entry,
from Data I/O.
AIM – Advanced Interconnect Matrix in the CoolRunner-II CPLD that provides the flexible
interconnection between the PLA function blocks.
Antifuse – A small circuit element that can be irreversibly changed from being non-
conducting to being conducting with ~100 Ohm. Anti-fuse-based FPGAs are thus non-
volatile and can be programmed only once (see OTP).
AQL – Acceptable Quality Level. The relative number of devices, expressed in parts-per-
million (ppm), that might not meet specification or be defective. Typical values are around
10 ppm.
ASIC – Application Specific Integrated Circuit, also called a gate array. Asynchronous logic
that is not synchronized by a clock. Asynchronous designs can be faster than synchronous
ones, but are more sensitive to parametric changes and are thus less robust.
ASSP – Application-Specific Standard Product. Type of high-integration chip or chipset
ASIC that is designed for a common yet specific application.
ATM – Asynchronous Transfer Mode. A very high-speed (megahertz to gigahertz)
connection-oriented bit-serial protocol for transmitting data and real-time voice and video in
fixed-length packets (48-byte payload, 5-byte header).
Back Annotation – Automatically attaching timing values to the entered design format
after the design has been placed and routed in an FPGA.
Behavioral Language – Top-down description from an even higher level than VHDL.
Block RAM – A block of 2k to 4k bits of RAM inside an FPGA. Dual-port and synchronous
operation are desirable.
CAD – Computer Aided Design, using computers to design products.
CAE – Computer Aided Engineering, analyses designs created on a computer.
CLB – Configurable Logic Block. Xilinx-specific name for a block of logic surrounded by
routing resources. A CLB contains two or four LUTs (function generators) plus two or four
flip-flops.
CMOS – Complementary Metal-Oxide-Silicon. Dominant technology for logic and memory.
Has replaced the older bipolar TTL technology in most applications (except very fast ones).
CMOS offers lower power consumption and smaller chip sizes compared to bipolar and
now meets or even beats TTL speed.
