Software Features:
TestDirector II TPS Development Studio Software for new TPS development and debug.
Python TD is a high level language similar to Mediator with Menu assisted syntax selection and options. When stepped through, it shows the generated graphical test patterns in a digital / analog / mixed signal workbench in another window.
Graphical Digital / Analog / mixed signal workbench can also be edited graphically and saved back in Python text.
Simulator can be invoked and expected logic states for output pins viewed in graphical mode.
Probe and Compare / Tailor traces facilities.
Learn mode for non-simulator based test programs.
Integration to Fault Simulation / Fault Insertion Test Program grading applications.
Integration to PCB Layout Gerber files and Digital image of the PCB created by CCD Camera (jpeg files) for probe guiding.
Back Tracking / Forward tracking algorithms and verification utilities.

In-Circuit Functional Test:
Qmax’s ICFT / QSM Software Package for In-Circuit test of digital / analog / mixed signal devices including cluster test using 22,000+ Qmax Models.
Test can be carried out using Clips / probes or nail bed.
Automatic extraction of device links from netlist / BDL file and verified during test.
Guard pins are automatically generated from the netlist / BDL file and prompted during test while testing Bus Devices and OC / OE devices.
QSM VI Learn / Compare for devices that cannot be modeled and simulated.

REVERSE ENGINEERING:
All the available Digital channels (Upto 320) can be used for Reverse engineering (Circuit Tracing and Schematic Generation applications) by using the Qmax Circuit Tracing software and when it is used along with EDWIN software package the user can reverse engineer the PCB by creating the schematic diagrams of the PCBs for which there are no circuit diagrams.
