ASIC Test Oriented Simulation Manual
Introduction
A challenge of testing application-specific ICs is creating test patterns by IC-design engineers who do not have deep
knowledge of the test-equipment and the related requirements and restrictions.
This manual bridges the gap by providing explanations, examples, and the necessary information to successfully set
up and perform simulations, which must be usable for testprogram-generation. It also explains the Microchip-internal
transformation-flow and the tools involved.
Terminology
The following terms are used frequently to identify specific test features and constraints:
Terminology Description
ATE Automatic Test Equipment (ATE). A tester is an ATE.
DUT Device Under Test (DUT)
A hardware product verified on the tester. It can either be a die on a wafer or a
packaged part.
Wafer Probe Testing operation for die on wafers.
It uses an additional ATE named Prober and a DUT interface named Probe Card.
Final Test Testing operation for packaged parts after assembly.
It uses a DUT interface named Load Board.
Test Cycle The interval of time (also called period) in which a test vector is presented to the DUT.
The beginning of a Test Cycle is the reference time for relative timings.
Test Vector A Test Vector consists of one signal state line in a test pattern.
It contains:
A period that delimits the beginning and end of the test vector, also called Test Cycle.
Signal states. Each signal state is represented by a symbol, which reflects its level and
direction (input or output mode for bidirectional). See Waveform File Format for more
information about symbols.
Timing data. Each signal has its own timing data. Inputs are stimulated at predefined
times (driven by the hardware of the tester), and outputs are sampled at predefined
Strobe times.
Test Pattern This is a set of test vectors, usually composed of one or two files: one for the signal
states and one for the timing information. They are the results from the conversion
of a simulation. The very first test vector starts at time 0, which is the absolute time
(reference) for the pattern.
