Shishpal Rawat, Chair
By Dr. Richard Ho and Dr. Ambar Sarkar, Co-Chairs of the UCIS Committee
After many years of dedicated work from both electronic design automation (EDA) vendors and members of the design community, the Unified Coverage Interoperability Standard (UCIS) version 1.0 will officially debut as an approved Accellera Systems Initiative standard at the Design Automation Conference 2012. The growing complexity of designs mandates that coverage data be shared among different tools to achieve full verification closure. UCIS is a first step towards the creation of a unified coverage standard that allows for interoperability of verification coverage data across multiple tools from multiple vendors. UCIS offers a standardized way to model and access verification coverage information.
UCIS is an industry initiative that has received contributions from EDA suppliers, EDA customers and facilitators. The participants all recognized that the community would benefit from a common and consistent application programming interface (API) and interchange format for coverage data as a step towards interoperability. Our vision is that standardization of the data interchange will enable innovation in both the EDA industry and in the design teams tackling the hardest verification problems. It is with pride that we count verification practitioners as well as all three of the major functional verification simulator companies as contributing members of this committee. Now that the standard has been released by Accellera, we hope to see UCIS help drive incremental productivity improvements through an emerging ecosystem of training, services, tools and new methods.
The challenge that UCIS is addressing is that verification of complex electronic circuits frequently requires the utilization of multiple verification tools, possibly from multiple vendors, and the deployment of different verification technologies. Coverage metrics are critical to measure effectiveness and to highlight verification shortcomings that require attention. Each verification process generates one or more coverage metrics which may be disjoint, overlapping or subsets. One of the key roles of the verification team is to gather, merge and interpret this multitude of coverage data to provide an overall assessment of verification quality and progress toward providing complete validation. Currently, no single metric consistently and globally tells engineers the exact status of verification. However, one step in the right direction is to bring all types of coverage metrics into a single database that can be accessed in an industry standard way.
UCIS provides an API and a XML-based interchange format that enables the sharing of coverage data between coverage producers and coverage consumers. It is designed to operate across a variety of tools including software simulators, hardware accelerators, symbolic simulations, formal tools or custom verification tools. The UCIS coverage database (UCISDB) is conceptually a single repository of all coverage data from all verification processes. It may, however, be one or more physical files in non-volatile storage, and it may be implemented differently by different tools.
For design teams, productivity improvements will come from the use of the API and the interchange format within applications or scripts to implement functions that consume coverage data. For example, we might imagine applications that use the API and the interchange format for producing reports, annotating the design, merging of coverage data, ranking of tests, or updating verification plans. Some applications may manipulate the data and hence be both a consumer and a producer.
As verification and analysis technologies improve, the individual coverage producers or consumers may change. The database implementation may also change, but the standardized API and the interchange format are intended to allow them to continue to operate together.
To facilitate the sharing of applications and scripts that utilize UCIS, Accellera will host an open source repository where engineers and companies can make contributions to be shared with the community, improving the usefulness and benefits of UCIS for all.
Naturally, EDA vendors will need to implement the UCIS API interface and the XML interchange format in their tools. Major vendors including Cadence, Jasper, Mentor Graphics and Synopsys have pledged support for UCIS beginning this year (2012). Each vendor's specific roadmap has yet to be announced, but the fact that such endorsing commitments have been made is great for our industry and an enabler for greater design and verification productivity.

Birds-Of-A-Feather Meeting: At a crossroads – developing the next generation Analog/Mixed-Signal language standard(s)
Tuesday, June 5, 2012, 7:00-8:30pm
Moscone Center, Room 300
Please sign up for this meeting in the Information Booth at DAC
Today's embedded and integrated systems interact more and more tightly with the analog physical environment, where digital HW/SW subsystems become functionally interwoven with analog/mixed-signal (AMS) blocks such as radio frequency (RF) interfaces, power electronics, or sensors and actuators. Examples are software defined radios, wireless sensor networks, and automotive applications, in which analog electronics are controlled, configured, or calibrated using digital techniques in hardware or software.
Historically, the hardware description languages Verilog-AMS and VHDL-AMS have addressed the analog implementation aspects but have limited capabilities to address the system-level design and verification challenges. From the digital perspective, SystemC and SystemVerilog focus on system-level design and verification, respectively. The SystemC AMS extensions are positioned to address the mixed-signal architectural design challenges, whereas SystemVerilog extensions are under development to include abstract analog signal representation in functional verification. Obviously, we are at a crossroads, where Verilog-AMS and VHDL-AMS are being updated and at the same time SystemC and SystemVerilog are expanding to support abstract AMS modeling styles. Should all of these AMS extensions remain compatible? Which elements are not yet addressed in the mixed-signal modeling and simulation domain but are essential for a next generation mixed-signal language? Can we focus on only one "mother HDL", or do we need more?
At this Birds-of-a-Feather session, these questions will be discussed and viable directions for the next step in AMS standards will be explored. AMS and RF system-level designers, circuit designers, verification engineers, and EDA vendors are invited to discuss the requirements and needs for the next-generation AMS languages.

As the verification needs in SystemC change and communication with other languages is more and more frequent, evolution complementing the existing standards (such as the SCV library) are required. Many efforts already exist with this goal; research projects, new libraries, etc. The purpose of this event is to share experience, gather new requirements, use cases, and applications that will need to be pushed for standardization. This event is organized around the SystemC Verification Working Group community, but is open to everyone.
Hosted Luncheon and Technical Presentation: Accellera Systems Initiative Rolls Out the Unified Coverage Interoperability Standard
Speaker: Dr. Richard Ho, Co-Chair of the UCIS Committee
Please be Accellera Systems Initiative's guest at a luncheon where we will present the forthcoming Unified Coverage Interoperability Standard (UCIS).
Coverage metrics are critical to measuring and guiding design verification. As designs have grown, increasingly advanced verification technologies, methods and additional metrics have been designed to form a fuller coverage model. There is currently no single metric that consistently and globally tells engineers the exact status of verification. But one step in the right direction is to bring all types of coverage metrics into a single database that can be accessed in an industry standard way. The UCIS facilitates the creation of a unified coverage database that allows for interoperability of coverage data across multiple tools from multiple vendors.
This presentation, intended for verification managers and tool developers alike, provides an introduction to and overview of the UCIS and how users plan to utilize it to enhance their verification flows. We provide a survey of many of the commonly-used coverage metrics and how they are modeled in the UCIS. The information that users will be able to access through the UCIS will allow them to write their own applications to analyze, grade, merge and report coverage from one or more databases from one or more tool vendors. We will also discuss the XML-based interchange format of UCIS, which provides a path to exchange coverage databases without requiring a common code library between tools and vendors.
