CDC-RDC analysis has evolved as an inevitable stage in RTL quality signoff in the last two decades. Over this period, the designs have grown exponentially to SOC’s having 2 trillion+ transistors and chiplet’s having 7+ SOC’s.
Different vendor tool abstracts are seen because of multiple IP vendors, even in house teams might deliver abstracts generated with different vendors tools.
The Accellera CDC Working-Group aims to define a standard CDC-RDC IP-XACT / TCL model to be portable and reusable regardless of the involved verification tool.
As moving from monolithic designs to IP/SOC with IPs sourced from a small/select providers to sourcing IPs globally (to create differentiated products), the quality must be maintained as driving faster time-to-market. In areas where the standards (SystemVerilog, OVM/UVM, LP/UPF) are present, the integration is able to meet the above (quality, speed). However, in areas where standards (in this case, CDC-RDC) are not available, most options trade-off either quality, or time-to-market, or both :-( Creating a standard for inter-operable collateral addresses this gap.
This tutorial aims to remind the definitions of CDC-RDC Basic Concepts and constraints, as well as the description of the reference verification flow, and addressing the goals, scope, structure & deliverables of the Accellera CDC Working Group in order to elaborate a specification of the standard abstract model.
A status related to the last LRM version open to public review by 2025-Q4, will be presented.
Accellera Systems Initiative is an independent, not-for profit organization dedicated to create, support, promote, and advance system-level design, modeling, and verification standards for use by the worldwide electronics industry. We are composed of a broad range of members that fully support the work of our technical committee to develop technology standards that are balanced, open, and benefit the worldwide electronics industry. Leading companies and semiconductor manufacturers around the world are using our electronic design automation (EDA) and intellectual property (IP) standards in a wide range of projects in numerous application areas to develop consumer, mobile, wireless, automotive, and other “smart” electronic devices. Through an ongoing partnership with the IEEE, standards and technical implementations developed by Accellera Systems Initiative are contributed to the IEEE for formal standardization and ongoing governance.
