Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “adt7420_i2c_bd.v provides the Verilog wrapper.”

A block of code is set as follows:

always @(posedge CK) begin
  stage  = D;
  Q      = stage;
end

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

module dff (input wire D, CK, output logic Q);
  initial Q = 1;
  always_ff @(posedge CK) Q <= D;
endmodule

Any command-line input or output is written as follows:

'timescale 1ps/100fs

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: “In the block design, right-click and select Add Module.”
