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 written purely in Python (noarch) and provides besides libraries also a plugin to the Spyder IDE.

Packages

The Semi-ATE project is maintained in this single repository, however it is released as a set of packages (all with the same version number) to accomodate the different use-cases.

3rd party packages needed:

mosquitto :

Installation (on a MiniSCT)

1. login as sct/sct
2. in the home directory there should be a directory repos
3. in repos there is a Semi-ATE directory (holding the relevant Semi-ATE git repositories)

• TCC_actuators : git clone

Run (on a MiniSCT)

1. Make sure you have a "test cell" configured as follows :

=== Installation of the packages can be achieved via conda or pip.

Installation using pip

Each package can be installed using python -m pip install <package-name>:

python -m pip install semi-ate-common
python -m pip install semi-ate-project-database
python -m pip install semi-ate-sammy
python -m pip install semi-ate-plugins
python -m pip install semi-ate-testers
python -m pip install semi-ate-spyder
python -m pip install semi-ate-apps-common
python -m pip install semi-ate-control-app
python -m pip install semi-ate-master-app
python -m pip install semi-ate-test-app

Or all at once:

python -m pip install semi-ate-common semi-ate-project-database semi-ate-sammy semi-ate-plugins semi-ate-testers semi-ate-spyder semi-ate-apps-common semi-ate-control-app semi-ate-master-app semi-ate-test-app

The semi-ate-project-database Package

This packages is used for dealing with Semi-ATE Projects. A Semi-ATE project consists of many definitions for describing hardware-setups, masksets, dies, packages, test programs, test flows, single tests and so on. All these definitions are stored in JSON format. To make migration possible. This package is required by the semi-ate-sammy package.
