How do I get the Verilog language standard?

问题:

How do I obtain the Verilog language standard? Is there a free version available? If not, what is the closest free resource that I can get?

I'm interested in:

• IEEE Std 1364-2001
• IEEE Std 1364-2005

I found paid versions on IEEEXplore, but the price ($175) seems a bit steep for someone who just wants to look up a couple things.

The closest you can get for free is the IEEE 1800-2012 SystemVerilog LRM, which you can download for free here:

• http://standards.ieee.org/getieee/1800/download/1800-2012.pdf

Don't get the 1800 LRM - SystemVerilog is not Verilog, and so much has changed that it's useless as a Verilog reference. You can find Draft 2 of the 2005 LRM free in various places - search for '1364-2005.pdf'. This is very close to the final 2005 LRM and is good enough. Don't know where you got the $175 price tag, though - I thought I paid a lot less for the printed and pdf copies a few years ago.
