Aspect-Oriented Programming with the e Verification Language by David Robinson

By David Robinson

What’s this AOP factor besides, really―when you get down to it―and can somebody please clarify what a side really is?

Aspect-Oriented Programming with the e Verification Language takes a realistic, instance dependent, and enjoyable method of unraveling the mysteries of AOP. during this ebook, you’ll learn the way to:

• Use AOP to arrange your code in a manner that makes it effortless to house the belongings you rather care approximately on your verification environments. ignore organizing by means of periods, and begin organizing via performance, layers, elements, protocols, useful insurance, checking, or something that you simply make a decision is critical to you
• simply create versatile code that eases your improvement burden, and offers your clients the ability to quick do what they should do along with your code
• really create a plug-and-play setting so as to upload and take away performance with no 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 sooner than you start a regression
• make the most of AOP to steer clear of these productiveness roadblocks that appear to plague all tasks on the so much inconvenient of times
• observe why “return” is evil, and a few different “gotchas” with the AOP positive aspects of e
All of the methodologies, information, and strategies defined during this ebook were constructed and established on actual tasks, with genuine 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 by way of following the recommendation given during this publication, you’ll achieve entry to the real energy of AOP whereas smartly warding off the trouble of operating all of it out your self.

• Use AOP to prepare your code in a manner that makes it effortless to house the belongings you fairly care approximately on your verification environments. ignore organizing through sessions, and begin organizing through performance, layers, parts, protocols, sensible insurance, checking, or whatever that you simply come to a decision is critical to you
• simply create versatile code that eases your improvement burden, and offers your clients the ability to fast do what they should do together with your code
• really create a plug-and-play surroundings as a way to upload and take away performance with out editing your code. Examples comprise the best way to use AOP to create pluggable debug modules, and a pluggable module that allows you to money that your testbench remains to be operating ahead of you start a regression
• make the most of AOP to ward off these productiveness roadblocks that appear to plague all initiatives on the so much inconvenient of times
• realize why “return” is evil, and a few different “gotchas” with the AOP gains of e

Sample text

Understanding the implications of what it says can be difficult. Anyone who has used e for more than a few weeks will probably know about all of the concepts mentioned here, but there are a few subtle points that you might not know about. I am using this chapter to take you through the language features that I consider the most important. I’m not attempting to cover all language features related to AOP, because they are not all equally important. If I haven’t discussed it here, it’s because I’ve never found a need to use it on a project.

Perhaps if you throw away the structure we already have and make signal connection a dominant concern, then your encapsulation will improve? 13 shows a class structure that would provide ideal encapsulation of your signal connections. This really isn’t any better than before. Again, a more pragmatic approach would normally be taken and multiple signal connect classes would be created — one per protocol or one per monitorand-checker per protocol. I think it’s fair to say that there is no “good” set of dominant concerns in this example that allows everything to be fully encapsulated.

If I haven’t discussed it here, it’s because I’ve never found a need to use it on a project. I do however, spend quite a bit of time explaining some of the nonobvious side effects of some of the features. For example, I talk about what really happens when you use when-inheritance and why returning from a method extension can be bad for your verification environment and bad for your sanity. So even if you know the e language syntax, I’d encourage you to at least skim through this chapter looking for the juicy bits that perhaps you don’t already know.
