What is HDL?

Hardware Description Language

High Level Language

• To describe the circuits by syntax and sentences
• As oppose to circuit described by schematics
• Allows designers to model the concurrency of process found in hardware

Widely used HDLs

• Verilog – Similar to C
• SystemVerilog – Similar to C++
• VHDL – Similar to PASCAL

Beware! HDL are not like “typical” sequential languages.
