Accellera Systems Initiative Announces SCE-MI 2.3

Updates give verification engineers more flexibility in their flows

Elk Grove, Calif., August 20, 2015 - Accellera Systems Initiative (Accellera), the electronics industry organization focused on electronic design automation (EDA) and intellectual property (IP) standards, announced today updates to the Standard Co-Emulation Modeling Interface (SCE-MI).

The newest version of the standard, SCE-MI 2.3, expands the set of SCE-MI compliant DPI function argument data types, giving users less restrictions and more opportunity for design portability; extends the debug interface to provide C-side access to HDL-side registers, making the design on the emulator more accessible and debug easier; and adds a new mechanism that enables a SystemVerilog HVL-side testbench to call DPI functions to HDL-side SystemVerilog and vice versa, removing limitations in emulation usage. 

“The goal of the SCE-MI standard is to reduce the effort necessary to get a system into an emulation or prototyping environment for verification,” stated Brian Bailey, Interface Working Group chair.  “With the new updates, we are removing restrictions, improving emulation debug capabilities and providing an enhancement to overcome unintended language limitations, giving users more flexibility in their verification flows.”

The Interfaces Working Group is seeking input on SCE-MI 2.3 from the community for consideration in the next revision of the standard.  To provide feedback on SCE-MI 2.3, please send email to  To download SCE-MI 2.3 for free, visit the Accellera Downloads page.
