Ni Requirements Gateway Doors

Since all our documents (requirements/V&V) are a consistent template, we have already had to write parsers and can easily insert our own documents into a project. Sometimes we have to write client parsers to extract client documents, but once you had to do it once. The hassle of creating/updating requirements documents is what keeps me from using them – the company I work with would prefer that I spend my time coding. Most of the projects I`ve worked on don`t have strict “written” requirements and things change regularly as the project progresses. My client usually tells me what they want and then sees that I have met the requirements when they “test” my code. I know that is not the best way to proceed and I wish I could change it, but for now, that is what I am sticking to. If you want to stick to basic software to document your needs, NI Requirements Gateway can scan text files for traceability information. In this case, your documents must conform to a formal syntax so that the software understands what it contains. NI Requirements Gateway comes with several sample projects and files. With these examples, you can see first-hand how the software interacts with supported requirements documents. Now that you are reasonably familiar with how the software handles requirements documents, let`s take a closer look at how NI Requirements Gateway interacts with National Instruments test, measurement, and control software.

We are a DOORS workplace, but I personally have had very little contact and training with it. I`m hesitant to say this in case the wrong people read it and take it out of context, but I find that our current system of requirements puts some pressure on development, mainly because of the different nature of the different tools we use: none of the tools we use work well with another in a LabVIEW context. I still think that we are better off with a system of requirements than without, I just know that the system should do much more for us than it can in its current form. There`s really no way for me to quantify code coverage, what requirements are missing, what code we need to check if we find a requirement not being met, etc. without doing things manually. I really hope to achieve some level of automation in the next release cycle, and I`ve been trying to figure out if NIRG can put us on that path. Of course, as Becky says, you`ll need your needs elsewhere first. We had some requirements in DOORS (integrates well with NIRG), but it was an expensive tool and we didn`t have all the licenses. Defining requests in Word (we`ve had many) or Excel (per se) is less desirable because they are not databases and it can be extremely difficult to track a request between document revisions.

Requirements Gateway allows you to specify applications, tests, and simulation models that correlate with documented requirements to capture traceability information. You can use Requirements Gateway to capture and compare project snapshots to see differences and see how requirements and coverage change over time. This application software integrates with LabVIEW, LabWindows™/CVI, and TestStand, as well as popular requirements documentation tools such as Telelogic DOORS, IBM Rational RequisitePro, and Microsoft Office. For those who have used it, I`m curious about how well it helps keep up with requirements and how much “overhead” it adds to your workload. Do you find it beneficial overall, or is it not worth the effort to recover? What other solutions have you tried? You can use Microsoft Word to define formatting styles. If you use the default font, font size, color, etc., the style is Normal. If you make formatting changes, you can save those settings with a style name. One way NI Requirements Gateway interacts with Microsoft Word is by searching for text in specific formatting styles.

Standard styles used by the software include Requirement_ID and Requirement_Text. When you use Telelogic DOORS for requirements management, your requirements are stored in modules in a database. There are two standard methods for NI Requirements Gateway to retrieve information from DOORS. In one case, NI Requirements Gateway uses the native ID of an object. In the other advanced interface of DOORS, an attribute called ReqID is referenced. The DOORS module shown in Figure 9 can be used with the advanced interface and is used in the project presented in the visit above. Whether you`re developing a user interface, test system software, or control application, you`re likely to base your design and development on specific requirements. With NI Requirements Gateway, you can learn how to collect and analyze requirements and traceability information from your software specifications and solutions. This gives you a quick, easy, and more comprehensive way to analyze and report on the progress of your development.

Ultimately, NI Requirements Gateway can be used to ensure compliance with internal, customer, or industry requirements and standards. While previous screenshots show NI TestStand and Telelogic DOORS, NI Requirements Gateway can also be used to collect traceability information from other software. You can use NI Requirements Gateway with the NI LabVIEW graphical development environment, LabWindows/CVI for ANSI C development, NI TestStand test management software, and MATRIXx design and development tools, as well as several popular requirements management and documentation tools such as Telelogic DOORS, IBM Rational RequisitePro, and Microsoft Word. Most engineering projects start with high-level specifications, followed by more detailed specifications as the project progresses. Specifications contain technical and procedural requirements that guide the product through each stage of development. In addition, working documents such as hardware schematics, simulation models, software source code, and test specifications and procedures must comply with and cover the requirements defined by the specifications. Tracking the relationship between requirements and test, measurement, and control software is critical to validating implementation, analyzing the full impact of changing requirements, and understanding the impact of test failures. Performing this coverage and impact analysis helps engineers meet their requirements and streamline development efforts. NI Requirements Gateway is ideal for applications where complex components are simulated or tested against documented requirements in industries such as automotive, defense, aerospace, and consumer electronics. This document provides a brief overview of NI Requirements Gateway and how NI Requirements Gateway interacts with applications to collect traceability information.
