I do FPGA design as part of my job. This is the most concise document I've found that covers everything you need to know to get started. Many verilog books just focus on the language. This short pdf focuses on how to use the language to do hardware design, which is what most people actually want to learn.
Many thanks for that link. I wrote VHDL for 10 years and sometimes had to interface to Verilog modules. I only know enough Verilog to read it and get a rough idea of what it does, sometimes asking for help from an expert.
