11. FPGA
The field-programmable gate array (FPGA) is a semiconductor device that can be programmed after manufacturing.
Instead of being restricted to any predetermined hardware function, an FPGA allows you to program product features and functions, adapt to new standards, and reconfigure hardware for specific applications even after the product has been installed in the field—hence the name "field-programmable".

12. HDL
A hardware description language or HDL is any language for formal description and design of electronic circuits and digital logic. It can describe the circuit's operation, its design and organization. It can verify its operation by means of simulation

13. VERILOG
Verilog HDL is a hardware description language used to design and document electronic systems. Verilog HDL allows designers to design at various levels of abstraction.

14. EVOLUTION OF VERILOG
Verilog was invented by Phil Moorby and Prabhu Goel during the winter of 1983/1984 at Automated Integrated Design Systems (renamed to Gateway Design Automation in 1985) as a hardware modeling language. Gateway Design Automation was purchased by Cadence Design Systems in Cadence now has full proprietary rights to Gateway's Verilog and the Verilog-XL simulator logic simulators.
