FAULT DIAGNOSTICS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18303219 titled 'FAULT DIAGNOSTICS
Simplified Explanation
The patent application describes a process for identifying defects in cells of a circuit.
- The process starts by receiving a layout of the circuit, which includes a first cell and a second cell separated by a boundary circuit.
- The process then determines bridge pairs, which are pairs of boundary nodes from the first cell and the second cell.
- The next step is to model any faults that may occur between the bridge pairs.
- Finally, the process generates a test pattern to detect these bridge pair faults.
Bullet points:
- Process for identifying defects in cells of a circuit
- Receives a layout of the circuit with a first and second cell separated by a boundary circuit
- Determines bridge pairs by pairing boundary nodes from the first and second cell
- Models faults that may occur between the bridge pairs
- Generates a test pattern to detect these bridge pair faults
Original Abstract Submitted
Process for determining defects in cells of a circuit is provided. A layout of a circuit is received. The layout comprises a first cell and a second cell separated by a boundary circuit. Bridge pairs for the first cell and the second cell is determined. The bridge pairs comprises a first plurality of boundary nodes of the first cell paired with a second plurality of boundary nodes of the second cell. Bridge pair faults between the bridge pairs are modeled. A test pattern for the bridge pair faults is generated.
