The ADM was first released with the support of fabrication rules and then enhanced in version 11.0 to support assembly rules and was well received by customers as a powerful and user-friendly tool, especially in comparison to its predecessor, the ERF manager.<\/p>\n\n\n\n
One setback for customers in the released ADM<\/a> was the lack of flexibility in the setup method of DFM constraint ranges. Some customers wanted to be able to get the analysis violations in the form of pass\/fail report and others wished to set explicit values for each of the DFM constraint range violation severity (red, yellow, green). <\/p>\n\n\n\n Therefore, in this November 2022 release we bring ADM to the next level with the advanced Constraints management<\/a>. With this new and exciting capability, the user can choose the level of simplicity in which each constraint is defined and reported, whether as fail\/pass or within ranges of severity.<\/p>\n\n\n\n The November 2022 release provide our users both on ADM level and on constraint level, to determine their own choice of Constraint management setting.<\/p>\n\n\n\n Three options are available for the user to choose from:<\/p>\n\n\n\n Top Tip:<\/u><\/strong><\/p>\n\n\n\n Before starting to work on individual constraints, ask yourself this:<\/p>\n\n\n\n Based on the answers to the above, go the ADM Preferences<\/em> window and select your default choice for new constraints setting<\/em>.<\/p>\n\n\n\n<\/div>\n\n\n\n A popular choice, especially amongst PCB designers is the pass\/fail approach, where the analysis reports only issues that violates a single threshold value. This approach is the best practice to implement when you are only interested in violations that will prevent your board from being manufactured.<\/p>\n\n\n\n If this is also how you and your company process DFM validation<\/a>, the best option for you it select is the Manage by Single value<\/em>.<\/p>\n\n\n\n The value entered is used as the analysis red severity threshold and the classification set<\/em> result distribution shows any issue that violates that threshold as red and all other measurements as green.<\/p>\n\n\n\n The two additional approaches, which for the most part serves companies and users which are interested in additional granularity in the severity of reported results, both refer to the analysis rule as a range of severities, instead of a single value.<\/p>\n\n\n\n The simpler approach of the two to implement and manage is the use of percentage to establish the threshold for the red and green severity. Here, all you need to do, is update the DFM constraint with a single limit value and with the desired percentage for the thresholds and the system already calculates and display for you both the red and the green values.<\/p>\n\n\n\n If you have explicit values that you wish to set for each of the severity thresholds your choice of election is manage by range<\/em> with detailed editing.<\/p>\n\n\n\n You can even choose whether you would like your entire table to be edited manually, or just some of the rows and leave others to use the percentage calculation.<\/p>\n\n\n\n Regardless of which of the two approaches you take, your reporting results will reflect the division of violations per the entire range.<\/p>\n\n\n\nWhat exactly are the new DFM Constraint management options?<\/h2>\n\n\n\n
