A new standard from the Institute of Electrical and Electronics Engineers Inc. (IEEE) addressed the challenge of verifying complex system-on-chip (SoC) designs from block to system levels.

The standard, IEEE 1647 - Standard for the Functional Verification Language 'e', is the first uniform open e-language specification. This language, which contains advanced constructs and facilities not found in other verification languages, is widely used by chip and computer makers worldwide.

According to IEEE, the standard creates a stable and well-defined language that provides a base for creating advanced e-based design automation tools to deal with today's massive verification tasks. It defines the 'e' language independent of implementation and specifies e-language constructs and their interactions with other simulation languages.

"Standardization of the 'e' language is a true milestone for the electronics industry," said Yaron Kashai, chair of the P1647 working group and engineering group director of verification research at Cadence Design Systems. "As chip features approach 65 nm or less, manufacturers need the most advanced methods for system verification so as to design and produce advanced SoCs economically and efficiently.

"IEEE 1647 seeks to meet this need. It arms engineers and others with a powerful, aspect-oriented language that allows extensible verification of involved electronic designs. It also gives the 'e' language the stability needed by the user community, which includes more than 75% of the world's largest electronics companies. This stability ensures that the language will remain viable as advanced tools based on it are developed."

IEEE 1647 was developed by a diverse working group and reviewed and approved by 55 experts from industry and academia. The 'e' language was pioneered by Verisity Ltd., which contributed the technology base for the new standard to the IEEE so an open 'e'-language standard could be created. Verisity was acquired by Cadence Design Systems in April 2005.
