Imagine what would happen if we were living in the world with no search engines. Wouldn’t we find ourselves lost in the deep information ocean, struggling to find the relevant stuff? The situation would be chaotic and nothing short of a nightmare. Cutting-edge search technology has given us unprecedented access to information at the click of a button—something that our previous generations could only dream of.
Web search utilities have become so seamless that we don’t realize how deeply they’re embedded in our daily life. Being an information engineer, I could go on for hours discussing this topic in depth. But that is not the agenda of this post. So let’s shift our focus back to the EDA world and see how search utilities are implemented in Cadence products and how they help make your work easy.
If your answer is yes, then you’ll be pleased to know that the Results Browser in Virtuoso® Visualization and Analysis has made the signal browsing easier by providing advanced search capabilities. The Results Browser is a data-bank of different types of simulation results databases that further include different types of signals. When too many databases are loaded in it, it’s not easy to find your choice of signal on which you want to perform graph analysis. This in-built search feature can't only save you from messing up with signals, but also rightly serves you with the signals you’re looking for.
The Search toolbar is not displayed when you open the Results Browser. Click the Search tab to view it.
Now, let's see how you can use this toolbar to search signals.
All the signals matching the search criteria will be listed right there. Isn’t it so simple?
If the search process is taking longer than the usual time probably because the result databases are huge, then you don't need to worry – you can now choose to stop the search process. Just click the Cancel button in the Searching pop up, as shown in the figure below. It is an additional functionality offered here that could save you time.
The Results Browser also has the Filter toolbar available that you can use to filter out some specific signals in the currently-opened database. It comes handy when you've a huge database and you want to view only selected signals in it. The Filter toolbar is right there at the bottom of the Results Browser when you open it for the first time. It looks similar to the Search toolbar and works pretty much the same way (see the figure below).
