Pattern matching (PM) was first introduced as the semiconductor industry began to shift from simple one-dimensional rule checks to the two-dimensional checks required by sub-resolution lithography.

As design nodes drop below 45nm, design rules are exploding in number and complexity, making design rule checking (DRC) harder and lengthier. What we have observed across the industry is that the ...

To help designers find complex features with a design implementation, physical verification and DFM tools may employ pattern matching techniques. That is, a designer can simply copy a particular ...

This file type includes high-resolution graphics and schematics when applicable. Michael White, Director of Product Marketing, Calibre Physical Verification products, Mentor Graphics In recent years, ...

This file type includes high resolution graphics and schematics. IC physical verification (i.e., design rule checking or “DRC”) used to be easy. In the good old days, you could run some ...

Analog circuits often use structures like differential pairs and current mirrors, where the matching of device characteristics such as the threshold voltage V t is important. Circuits using these ...

Python, for all its power and popularity, has long lacked a form of flow control found in other languages—a way to take a value and match it elegantly against one of a number of possible conditions.

Wildcards have been around forever. Some even claim they appear in the hieroglyphics of the ancient Egyptians. Wildcards allow you to specify succinctly a pattern that matches a set of filenames (for ...
