Instructions

1. Instruction Manual

There is a manual in PDF format that covers almost all functions of XTAP. You can find this user’s manual at the menu bar of XTAP in the following menu: “Help” –> “How to use (C)”. 

The Instruction Manual is also available here: Instruction Manual.

2. Test Cases

XTAP comes with test cases (sample files) for various fields. These test cases are located in the folder “C:\XTAP\work\Examples”, if you have installed XTAP in the default installation folder (“C:\XTAP”). There is an individual folder for each test case. In each folder there is a PDF file describing the test case.

A unified version of PDF file including all test cases is available here: Test Cases of XTAP.
