All SYNOPSYS™ documentation is now contained in the download file. That means it is always up to date, and you don’t have to thumb through a paper copy when you want to look up something. We recommend that new users print out the Tutorial Manual, read it completely, and work the simple examples. The second component, the User’s Manual, is too long to print — but it is completely cross-referenced so you can find any topic, within seconds, on your monitor screen. When you run the program, type HELP UM to open the User’s Manual, or HELP TM to open the Tutorial Manual. There are many ways to open the manual to a desired topic instantly. Read about them in Section 13.1 of the manual. This is probably the friendliest help feature in the software industry.
