Verilog-1995 is the first IEEE standardized version of the Verilog Hardware Description Language. Though Verilog-1995 has been around for many years, it is by no means out-of-date. Many engineering companies still use the 1995 version of the Verilog standard to ensure that Verilog models are portable to the widest possible set of Verilog simulators, synthesis compilers, and other engineering tools.
Verilog-2001 is the second generation of the Verilog Hardware Description Language (SystemVerilog-2005 is the third generation). This version of the Verilog Quick Reference Guide by Sutherland HDL, Inc. is stored as a PDF document.
