  1. What is the next level of abstraction? Alon Gluska Intel iMPG, Haifa

  2. Why was it difficult to go to HLM? • Validation is the problem of the validators…

  3. Why was it difficult to go to HLM? • Validation is the problem of the validators… • Architects need only to write specs

  4. Why was it difficult to go to HLM? • Validation is the problem of the validators… • Architects need only to write specs • Designers need to write code (and insert bugs of course)

  5. Why was it difficult to go to HLM? • Validation is the problem of the validators… • Architects need only to write specs • Designers need to write code (and insert bugs of course) • It is the validators that needs to cope with all the mess

  6. Why was it difficult to go to HLM? • Validation is the problem of the validators… • Architects need only to write specs • Designers need to write code (and insert bugs of course) • It is the validators that needs to cope with all the mess • HLM requires a complete change in the way we do design • Methodologies, expertise, mindset

  7. Why was it difficult to go to HLM? • Validation is the problem of the validators… • Architects need only to write specs • Designers need to write code (and insert bugs of course) • It is the validators that needs to cope with all the mess • HLM requires a complete change in the way we do design • Methodologies, expertise, mindset • Can we afford not to change?

  8. Essential features of higher level • HLM represents a holistic approach • Architects develop highly abstract models • Designers add more details to the abstract model • Making is cycle accurate and synthesizable • Coping with timing, power and other low level details • Validation reuse collateral along all abstraction levels • HLM is beneficial for • Better specifications (w.r.t. English documents) • Early software development • Integrations of IPs into systems (SOC) • And more • But these are not the real promise…

  9. Essential features of higher level • Need to completely switch to HLM • With no need to go through RTL • Dramatically reduce the details in design • Or otherwise, we do very little… • Requires translation and formal equivalence from HLM to gate-level • Taking power, timing and layout into consideration • We are not there yet • Semantic of HLM languages, tools and methodologies • But we will get there soon
