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 ...

Pattern matching is best known for its use in detecting lithographic hotspots, but it’s also widely used across all physical verification flows, and has expanded into design-for-manufacturing (DFM) ...

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 ...
