checksum

A checksum is a summation of bits or digits generated according to an arbitrary formula used for checking data integrity. To verify that the data represented by a checksum number has been entered correctly, verify that the checksum number generated after processing is the same as the initial number.

CLB

The Configurable Logic Block (CLB). Constitutes the basic FPGA cell. It includes two 16-bit function generators (F or G), one 8-bit function generator (H), two registers (flip-flops or latches), and reprogrammable routing controls (multiplexers).

CLBs are used to implement macros and other designed functions. They provide the physical support for an implemented and downloaded design. CLBs have inputs on each side, and this versatility makes them flexible for the mapping and partitioning of logic.

CCLK pin

The CCLK pin is the XChecker pin that provides the configuration clock for the device or devices during a download.

clock

A clock is a signal that represents the time that a wave stays at a High or Low state. The rising and falling edges of a clock square wave trigger the activity of the circuits.

clock buffer

A clock buffer is an element used to increase the current or drive of a weak clock signal and consequently increase its fanout.

clock enable

A clock enable is a binary signal that allows or disallows synchronous logic to change with a clock signal. When enabled, this control signal permits a device to be clocked and to become active. There are four different states. The two active High states are CE 0 disabled and CE 1 enabled. The two active Low states are CE 0 enabled and CE 1 disabled.

clock skew

Clock skew is the time differential between 2 or more destination pins in a path.

CMOS

Complementary Metal Oxide Semiconductor (CMOS). Is an advanced IC manufacturing process technology characterized by high integration, low cost, low power, and high performance.
