Ensuring Interoperability Ensures any capability or enhancement done in the analog or the mixed signal part of the AMS language works with existing standards Interoperability is key: Ease of understanding; uniform implementation of the particular implementation, developing portable design

Plans to integrate Verilog-AMS with SV as part of IEEE p1800 dot standard Subcommittee to look at outstanding enhancements and capabilities for mixed signal constructs This effort will specifically look at the mixed signal items that have not been resolved in LRM2.3 and will be driven by Marq Kole from NXP This activity will be in parallel to SV-AMS merger and is kept disconnected in terms of release for enabling maintenance and improvement of language from merger activities Extending SV assertions to AMS Need to extend the current SV assertions to the mixed signal language as part of the SV- AMS integration work

The plan is to have it as a “corporate standard” within the IEEE organization The SV-AMS committee will work on integrating the Verilog-AMS v2.3 with P1800-2009 IEEE standard. The next major version (internal name LRM v3.0) will be released as dot standard within P1800 The committee will also oversee the efforts of driving the SVA extensions to Analog and the Mixed-signal behavior working groups The Verilog-AMS v2.3 can be donated to the IEEE and can be used as the basis for the P1800 integration work Open Questions: The release of the SVA extensions to Analog and improvements to mixed signal behavior need to be de-linked from merger activities Is it possible to release work from the sub-committees under Accellera Organization (LRM 2.4, etc). This is very likely and needs to be enabled since SV-AMS merger might be bigger effort than the sub-committee efforts
