Automatic Design Validation of Integrated Circuits Using E-Beam

Objetivo

The objective of ADVICE was to produce a prototype system capable of automatic error diagnosis of VLSI devices.
The chosen approach was based on using the observability facilities of Ebeam equipment.
The objective of ADVICE was to produce a prototype system capable of automatic error diagnosis of very large scale integration (VLSI) devices. The chosen approach was based on using the observability facilities of electron beam equipment. In order to achieve the above, the following was carried out:
interfacing to computer aided design (CAD) software;
pattern recognition for automatically positioning the electron beam;
development of a global methodology to define the diagnostic strategy;
development of new hardware for enhancement of electron beam performance.

The following problems were solved:
computer control of the electron beam system;
identification of circuit elements;
test pattern generation for electron beam debugging;
design for electron beam testability;
electron beam equipment development.
In order to achieve the above, the following was carried out:
-interfacing to CAD software
-pattern recognition for automatically positioning the Ebeam
-development of a global methodology to define the diagnostic strategy
-development of new hardware for enhancement of Ebeam performance.
The following problems were solved:
-computer control of the Ebeam system
-identification of circuit elements
-test-pattern generation for electron beam debugging
-design for electron beam testability
-electron beam equipment development.
Exploitation
Following the completion of the project, which included the definition and investigation of all aspects for the design and implementation of a fully computer-controlled Ebeam testing system, the three industrial partners have installed systems that are n ow fully operational on their premises.
Some of the key features already included in the systems are:
-interfaces between CAD and Ebeam systems
-pattern recognition
-hardware and software for computer control.
The results satisfy all the realistic goals set at the beginning and following the first phase. These results are at least state of the art as exemplified at the various presentations and demonstrations given by the partners.
The Ebeam design validation and testing technique is a new and very promising one. Its impact and the time horizon for industrial applications depends strongly on the refinement of this or other competing techniques (egscandesign) that may emerge. British Telecom are selling waveform averaging equipment based on one of the results of the project.
