  1. Personal Opinion onFuture Role of Formal Verification in Hardware Industry W. Paul Universität Saarbrücken wiss. Gesamtprojektleiter bmb+f Projekt Verisoft

  2. 3.5 Mio €/year Partners: infineon,… Mission (industrial) Verify high end controllers Mission (academic) Verify stacks Processor, devices, drivers, compiler, kernel, OS, client/server, TCP, real time…. 2003: verified lab prototype (processor, 1.5 Mio gate equivalents) Verisoft 1: 2003-2007

  3. Industrial Processor VerificationOneSpin Solutions (2006) • Tools tightly coupled to production flow • Prove hundreds of properties by bounded model checking (> 90 % effort) • Combine to correctness proof in interactive prover (< 10 % effort) • Cheaper than conventional testing • New masks… • 14 Mio € Venture Capital

  4. Conclusions 1 • Tools tightly coupled to production flow • It can be done; do it. • Cheaper than conventional testing • Use formal methods as soon as finding bugs by testing becomes slow • Everybody does it for FPUs. • among the most complex constructions in computer science • Learn to do it for more units

  5. Formal proof of kernel written in C with in line assembler code expected 2007 (Verisoft 1) Mission (Industrial) Verify and certify OS related product code, Partners Automotive Avionics Microsoft High end processors Verisoft 2 (2007-2010, planned)

  6. A Grand Embarassement • High end processors are flagship products of our field • We presently don‘t know how to define their ISA formally (i.e. don‘t know what exactly they are doing) • Necessary for complete formal verification • We better fix that asap

  7. Mathematics Literacy in CS • Very much of applied computer science as a whole can be presented as a mathematical theory • Faster/more precise than usual hand waving • applied CS textbooks will have mix of text/pictures/math familiar from classical engineering disciplines

  8. Conclusion 2The Mathematically Clumsy CS Engineer • Endangered species • Near future: jobs moved off shore • But: off shore countries educate mathematically literate CS engineers… • Hire mathematically literate engineers as quickly as you can • Put pressure on universities to educate them
