Si2 Interoperability Guide V2.0 Available for Download

Recently, the Silicon Integration Initiative (Si2) announced the availability of the Interoperability Guide for Power Format Standards V2.0. This is an important milestone of power format interoperability between IEEE 1801-2009 and the Common Power Format (CPF).

This update was triggered by the Si2's CPF 2.0 release earlier this year. CPF 2.0 is a major CPF release on top of the previous CPF 1.1 and 1.0 releases. Many new features were introduced in CPF 2.0. To learn more about CPF 2.0, check out the online tutorial.

Another major accomplishment of this new version of CPF is that it has some noticeable enhancements to improve the interoperability with IEEE 1801. For those who are close to the two formats, here is a short list of enhancements made in CPF 2.0 to improve interoperability:

  • Support -pg_type in create_global_connection
  • More flexible mode specification to model functional modes
  • Ability to force isolation and shifter insertion on crossings that do not require isolation by default
  • Ability to model more types of state retention logic
  • Ability to enable/disable power aware simulation semantics

The recently released Interoperability Guide V2.0 is an update of the previous version with changes included. For those who are using a low power design flow with mixed power format languages, the new release is a must read.
