1 Overview
In order to optimally fulfill the contacting requirements for In-circuit tests (ICT) various test
probes are available. These differ in terms of height, size, tip style and type of connection. On
the PCB the corresponding contact areas (testpoints) must reflect these requirements.
Testpoint to Testpoint constraints
Rules may be specified as center to center or pad to pad rules. If several probe sizes are
used for the PCB, the spacing constraints may further depend on pad size.
Testpoint to Component constraints
The testpoints must not come to close to component boundary in order to avoid damage.
Spacing constraints do not only depend on probe size, but also on component height.
Tall components usually require a larger spacing from the boundary than lower
components.
Advanced Testpoint Check is a toolbox application which addresses various rules for testpoint
checking.
Features are
Testpoint to Testpoint checking
Testpoint to Component checks based on height depending spacings
Visualization of restriction areas
DRC marker generation
Constraints reuse through configuration files
