Verilog

Verilog is language commonly used in designing digital systems. It is a hardware description language, which means that it is substantially different from any other language you might have encountered so far. Even though it does have control flow statements and variables, it relies primarily on logic functions. It is a textual format for describing electronic circuits and systems.

Verilog has evolved as a standard hardware description language. Verilog offers many useful features for hardware design. It is easy to learn and easy to use as it is similar to C Programming language. Designers with C Programming experience will find it easy to learn Verilog.

Comparator

A digital comparator or magnitude comparator is a hardware electronic device that takes two numbers as input in binary form and determines whether one number is greater than, less than or equal to the other number. Comparators are used in central processing units (CPU) and microcontrollers. Examples of digital comparators include the CMOS 4063 and 4585 and the TTL 7485 and 74682-'89.
