Method and system for fixing violation of layout

A system, comprising:

• a memory configured to store computer program codes;
• and
• a processor configured to execute the computer program codes in the memory to:
• classify a first violation of a first layout into a first class of a plurality of predefined classes, according to data of the first violation;
• automatically assign a first operation of a plurality of pre-stored operations to the first violation, according to the data of the first violation;
• generate a second layout based on the first layout and the first operation;
• classify a second violation of the second layout into a second class of the plurality of predefined classes, according to data of the second violation;
• automatically assign a second operation of the plurality of pre-stored operations to the second violation, according to the data of the second violation;
• generate a third layout based on the second layout and the second operation;
• adjust the first operation and the second operation according to a fix rate;
• and
• generate the fix rate according to a first number of first violations of the first layout.

A method, comprising:

• classifying a first violation on a layer of a first layout into one of a plurality of predefined classes, according to a plurality of first features of the first violation;
• selecting a first operation from a plurality of pre-stored operations, according to the plurality of first features;
• and
• modifying the first layout according to the first operation to generate a second layout,
• wherein classifying the first violation comprises:
• when a number of violations on the layer is larger than or equal to a preset number and when a metal density of the layer is larger than or equal to a preset value, classifying the first violation into a first class corresponding to routing congestions;
• and
• when the number is smaller than the preset number, classifying the first violation into a second class different from the first class,
• wherein the preset value is ranged in 0.25-0.3.
