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 the complexity of IC designs continues to grow, moving critical checks earlier in the design cycle helps designers identify and resolve issues before they escalate, streamlining the overall ...

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 ...

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 ...

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 ...

As we all know, the back-end design of layout implementation known as integrated circuit (IC) layout — is simplistically divided into ASIC-style flow and full-custom flow. This article will try to ...
