Semi-ATE

Semiconductor Automated Test Equipment

Semi-ATE is a tester- and instruments AGNOSTIC framework for Semiconductor ATE ASIC testing projects.

This means that the system is not build around a specific instrument (let's consider an ATE tester for a moment as a super instrument😋), it rather focuses on organizing semiconductor testing in such a way that all use- (and special) corner cases have their well known place. This enables the users (read: DE's, TCE's, TE's & PE's) to focus on the REAL work, being the writing of good, fast and stable tests. Organizing tests into test-programs and test-programs in to flows is handled by wizards, so the only code that needs writing is the actual test! (motto: Code is our enemy)

The Semi-ATE package is writen purely in Python (noarch) and provides besides libraries also a plugin to the Spyder IDE.

Installation

Setup Semi-ATE

Setup on Windows

Assuming that the current directory is Semi-ATE root.

open a Windows command prompt(CMD) and run the following command:

Powershell -ep Unrestricted -file setup.ps1

Before starting the applications

Once, each step of the setup.ps1 is succeeded the following steps must be checked:

1. testprogram name must be adapted in ATE/Tester/TES/apps/le123456000.xml, therefore replace the 'PROGRAM_DIR#' in 'STATION' section with the following:

   <missing_part>/smoketest/smoke_test/src/HW0/PR/smoke_test_HW0_PR_Die1_Production_PR_1.py 
   

   you will find the smoketest directory in the root level of Semi-ATE directory

   <missing_part> must be replaced with the missing path piece to fit the absolut path of the test program

2. lot number must be adapted in ATE/Tester/TES/apps/le123456000.xml. Therefore, 'LOTNUMBER' field muss be fit. Assuming the xml file name is 'le123456000.xml', LOTNUMNBER field should look as follow:

   <LOTNUMBER>123456.000</LOTNUMBER>

3. After configuring xml-file there still one thing to do. open the master configuration file (ATE/Tester/TES/apps/master_configuration_file.json) and replace the 'filesystemdatasource.jobpattern' key-value with the xml file name.

   Based on the example above, this should look something like this: 'filesystemdatasource.jobpattern': 'le123456000.xml'

   ---

   NOTE
   As soon the xml-file name is changed, make sure to update the lot number as discribed in 2) and 3) !

   ---

4. in case you generate your own test-program you need to make sure that the bin mapping inside the XML-file mappe those sbins the test-program uses.

5. make sure you got an mqtt-broker runs in your local machine. mosquitto can be used for this purpos.

   For further informations please contact your IT.

Running Spyder-IDE

before you can use spyder you should have already cloned the repository from git (could be done using the 'setup.ps1' script)

If already done, than switch to spyder directory and run the following command:

python bootstrap.py
