What are DRC & how will you fix them?

DRC stands for “design rule check.” In the context of integrated circuit (IC) design and fabrication, a DRC is a set of rules that specify the minimum dimensions, spacing, and other design constraints that must be followed in order to ensure that an IC will function correctly.

When an IC design is prepared for fabrication, it is run through a DRC process to ensure that it meets all of the necessary design rules. If the design fails the DRC check, it means that there are errors or violations of the design rules that need to be corrected before the design can be sent for fabrication.

To fix DRC errors, the designer must go back and modify the design to correct the errors and bring it into compliance with the design rules. This may involve adjusting the sizes or positions of various features on the IC, or adding or removing elements as needed. Once the errors have been corrected and the design passes the DRC check, it can be sent for fabrication.
