 This section will introduce Verilog for readers who may not be familiar with the language, concentrating on the features that are used in the output of \vericert{}.  Verilog is a hardware description language (HDL) and is used to design hardware ranging from complete CPUs that are eventually produced as an integrated circuit, to small application-specific accelerators that are placed on an FPGA.  Verilog is a popular language because it allows for fine-grained control over the hardware, and also provides high-level constructs to simplify the development.
 
 Verilog behaves quite differently to standard software programming languages due to it having to express the parallel nature of hardware.  The basic construct to achieve this is the always-block, which is a collection of assignments that are executed every time some event occurs.  In the case of \vericert{}, this event is either a positive (rising) or a negative (falling) clock edge.  All always-blocks triggering on the same event are executed in parallel. Always-blocks can also express control-flow using if-statements and case-statements.
