What is this AOP factor besides, really-when you get all the way down to it-and can anyone please clarify what a facet truly is?Aspect-Oriented Programming with the e Verification Language takes a practical, instance established, and enjoyable method of unraveling the mysteries of AOP. during this booklet, you will find out how to:. Use AOP to arrange your code in a fashion that makes it effortless to house the belongings you relatively care approximately on your verification environments. ignore organizing by way of periods, and begin organizing by way of performance, layers, parts, protocols, useful insurance, checking, or something that you simply come to a decision is critical to you. simply create versatile code that eases your improvement burden, and provides your clients the facility to fast do what they should do along with your code. actually create a plug-and-play surroundings so as to upload and take away performance with out enhancing your code. Examples comprise tips on how to use AOP to create pluggable debug modules, and a pluggable module that permits you to cost that your testbench continues to be operating prior to you start a regression. make the most of AOP to keep away from these productiveness roadblocks that appear to plague all tasks on the so much inconvenient of occasions. detect why "return" is evil, and a few different "gotchas" with the AOP gains of eAll of the methodologies, guidance, and strategies defined during this booklet were built and confirmed on actual initiatives, with actual humans, genuine schedules and the entire linked difficulties that include those. in basic terms those that labored, and labored good, have made it in, so through following the recommendation given during this e-book, you are going to achieve entry to the genuine energy of AOP whereas smartly fending off the hassle of operating all of it out your self. .

Example text

Extend my_class{ my_method() is {}; my_method() is first{}; my_method() is also{}; my_method() is only{}; }; // // // // The root method is first advice is also advice is only advice Event join points. Advice can be added to events, but only the is only type of advice. That means you can replace the definition of an event, but you can’t add to an existing event. extend my_class{ event my_event is only cycle @clk; }; 35 2 AOP in e Cover group and cover item join points. Advice is added to cover groups and cover items using the using also keywords, which allow you to add new options to the group or item.

What do I do? Solution Extend the class as described earlier and add your new noncoverage member to the class. The introduction you make uses exactly the same syntax as it would if you were adding it to the class when it is defined. Discussion Adding a method, field, or event to a class as part of an extension is called an introduction. Once the class extension has been made, no special syntax is required to actually make the introduction. You just declare your new member as you would normally do.

Once a bug has been fixed or the new functionality added, the original source code should be updated with the changes. However, this can now be done at a suitable time of your choosing. 6 What are aspects? — Part II The definition I gave earlier of an aspect being a crosscutting concern is good, but it could be better. It seems like the most complex part of AOP is coming up with an exact definition for an aspect. This is not helped by the fact that the word “aspect” is used for two different meanings.
