Custom Compiler In-Design Assistants (Part 1)

On-line Design Rule Checking (DRC) is nothing new. The technology has been in use for years in a variety of different layout editors and yet nearly every layout engineer has a love/hate relationship with it. Why? Well it really comes down to the use model and the responsiveness of the application.

At the beginning of the design process, layout engineers love on-line DRC. But as the design progresses, the relationship begins to sour. The problem is that as the layout gets bigger and more complex, the performance invariably starts to fall off until it reaches a point where it becomes unacceptable and the layout engineer simply turns it off and resorts to running the occasional batch checks.

To really be effective, on-line DRC has to be an interactive tool that is run often during the layout process, so, as such it needs to have a simple use model and have a fast response. The engine needs to be ‘built-in’ to deliver the required performance and the feedback needs to be comprehensive enough to enable the layout engineer to quickly fix the violation.
