DIGITAL VERIFICATION Services

Verification is one of the key issues in IC design and development impacting product schedules and timelines. We offer a wide range of ASIC verification services which help customers to achieve working silicon the first time.

Rapid progresses in silicon technology offer excellent possibilities in including digital / analog cells, embedded processors, high speed IO, memories, in-house / 3rd-party IP and more onto a single device. Our verification resources understand the challenges involved in such designs and work closely with customers to offer specific solutions that help in achieving the required capability on a complete chip.

Identification and preparation:

During the development stage of a specification, the identification of verification activity is done parallel. This enables the designer to make sure that the specification is verifiable. So a test engineer can start detailed test plan and procedures. Any changes in the specification should be communicated.

• Identifying the best approach to conduct verification, define measurement methods, required resources, tools, and facilities.

• The completed verification plan will be reviewed with the design team to identify issues before finalizing the plan.

Developing:

• The test case development will coincide with SDLC methodology implemented by a project team. A variety of test methods are identified during this stage.

• The design inputs must be developed including simplest verification activities which are unambiguous and verifiable.

• Verification time shall be reduced when similar concepts are conducted in sequence. Even the output of one test can be used as input for subsequent tests.

• Tractability links are created between test cases and corresponding design inputs, to ensure that all the requirements are tested and the design output meets the design inputs.

Reports:

• This activity is performed at the end of each phase of verification execution.

• The design verification report gives the detailed summary of verification results which includes the configuration management, test results for each type of testing and issues found during the verification activity.

• Design verification traceability report is created between requirements and corresponding test results to verify all the requirements have been tested and provided with appropriate results.

• Any non-conformance will be documented and appropriately addressed.

• Reviews are done upon the completion of design verification activity and are approved respectively.

• Some of the designs may be validated by comparing with similar equipment performing similar purpose. This method is particularly relevant for validating configuration changes for existing infrastructure, or standard designs that are to be incorporated in a new system or application.

• Demonstration and/or inspection may be used to validate requirements and other functionality of the product.

• Analyzing the design can be done such as mathematical modeling, a simulation which can recreate the required functionality.

• Tests are performed on the final design that validates the ability of the system to operate as per the specified design.

• Test plan, execution, and results should be documented and maintained as a part of design records. Thus, Validation is a collection of the results of all validation activities.

• When equivalent products are used in the final design validation, the manufacturer must document the similarity and if any difference from initial production.
