- Subject: Postdoc vacancy for multi-rate / protocol verification
- in IC-design, second round.
-
- Several months ago, a postdoc vacancy has been created by a
- proposal of the Philips Research Lab Eindhoven (The Netherlands),
- that has been accepted by the European Communities program
- "Human Capital and Mobility".
-
- The technical part of the proposal is appended to this announcement.
-
- We search for skilled candidates, who have received a PhD or are
- about to receive a PhD in computer science, mathematics or electronic
- engineering and who are inhabitants of a non-Dutch EC country.
-
- In this second round, we expect candidates to apply within 2 months.
- The application letters will be dealt with in the order they come in.
- The 18-month postdoc period must start between Januari 1st
- and June 1st, 1993. The conditions of employment,
- which are quite favourable, are determined by the EC.
-
- An application can be send in by (e)mailing an application letter,
- containing your CV, motivation to apply, qualification, etc., to
- the address below. When sending email, latex source is fine.

- TITLE
-
- Formal verification of multi-rate IC-designs.
-
- DETAILED DESCRIPTION OF THE PROJECT
-
- The aim of the project is to solve fundamental problems that
- prevent the verification of multi-rate IC-designs.
- A multi-rate IC is a digital Integrated Circuit of which
- different parts run on different clock frequencies,
- and for which no simple timing relation
- between the constituent parts exist.
- Proving correctness of the communication between these parts
- is difficult. From a functional point of view,
- the communication can be multi-synchronous or even asynchronous.
- A digital signal processor for example, can consist of
- different parts running with different sampling frequencies,
- again with different clock frequencies, and the communication
- can be multi-synchronous, or ``asynchronous" via
- synchronised interrupts.
-
- Until now, formal verification methods for IC design focus
- on single clock systems only. Recent advances in this area,
- such as for Finite State Machine verification and Retiming
- verification are a step forward in verifying single clock parts,
- but they do not address multi-rate IC-designs.
- There is no known method to verify non-trivial multi-rate designs
- in a reasonable way.
- The verification method currently applied, based on simulation,
- is insufficient to get a reasonable impression of the correctness
- of the communication between the constituent parts.
- Only a very limited set of interrupts and input patterns
- can be simulated because of the long simulation times that are needed.
- Checking synchronisation and setup procedures for every possible
- situation is therefore prohibitive.
- The only reasonable ``verification method" remaining is to test
- how the actual IC behaves after it has been processed.
-
- The research project will focus on the fundamental question of
- how the communication can be modeled, and how the implementation
- can be proven correct, while assuming that the constituent
- (single clock) parts of the IC design are correct.
-
- The strategy for tackling the verification problem in
- multi-rate IC designs will be based on exploiting the knowledge
- of formal verification methods in strong combination with
- IC design expertise and know-how. In this way, it is expected
- that parts of the verification problem will be solved,
- in particular those items that are most relevant for the IC designers.
-
-
- RELEVANCE OF THE PROJECT TO THE TRAINING OF YOUNG RESEARCHERS
-
- The Philips Research IC Design Centre offers the researcher
- an ideal environment to attack this challenging problem.
- It has an outstanding reputation for
- IC design research and CAD for VLSI in general,
- and for IC design verification in particular.
- It combines both the academic freedom to explore new ideas
- and the challenge to apply the ideas on industrial designs.
- In this sense we have shown several times that
- the combination of our CAD research
- and IC design expertise leads to unique CAD products
- that are very useful in industrial design environments.
-
-
- INDUSTRIAL, ECONOMIC AND SOCIAL RELEVANCE OF THE RESEARCH
-
- Continuous advances in IC technology
- allow the integration of functions of ever growing complexity.
- The number of single chip multi-rate system designs is growing rapidly,
- but its verification is at present already a major bottleneck.
- Therefore, multi-rate verification has become extremely important
- to guarantee first time right IC designs, and the relevance
- grows even more with time. First time right IC designs are essential
- to reduce the time to market of new electronic products.
