Assignee: TSMC NANJING COMPANY, LIMITED
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 17:
18. An integrated circuit (IC) device design system comprising:
at least one processor; and
at least one memory including computer program code for one or more programs, the at least one memory and the computer program code being configured to, with the at least one processor, cause the IC device design system to:
identify a net comprising a pin failing a test to determine an antenna effect;
identify a cell comprising the pin failing the test to determine the antenna effect;
create an engineering change order (ECO) script configured to insert a diode configured to address the antenna effect based on the identified net and cell, wherein the diode is inserted at a first metal layer; and
updating the ECO script to move the diode to a second metal layer below the first metal layer.
