Design Verification and sign-off
Design Verification with DFT ATPG and other tools and Design Verification with LEC, sign-off, and post-silicon validation to provide a more comprehensive overview of the design verification process.
Design verification is a crucial part of the integrated circuit (IC) design process, which ensures that the IC meets its performance, functionality, and testability requirements. Design verification involves a series of verification steps that include DFT ATPG, LEC, sign-off, and post-silicon validation.
Design verification with DFT ATPG and other tools involves the following steps:
DFT Insertion: DFT structures are inserted into the IC design to make it easier to test.
ATPG Pattern Generation: ATPG tools generate test patterns to detect faults or defects in the IC.
Fault Simulation: The test patterns are simulated to verify that they can detect faults in the design.
Debugging: If any issues are identified during fault simulation, the root cause of the problem is isolated and resolved.
Coverage Analysis: Coverage analysis is performed to ensure that the test patterns cover all possible faults or defects in the design.
LEC: LEC is performed to ensure that the RTL design and netlist design are functionally equivalent.
Sign-off: The design is reviewed and approved for fabrication.
Post-Silicon Validation: The IC is tested to verify that it meets its performance and functionality requirements.
Design verification with LEC, sign-off, and post-silicon validation involves the following steps:
LEC: LEC is performed to ensure that the RTL design and netlist design are functionally equivalent.
Sign-off: The design is reviewed and approved for fabrication.
Post-Silicon Validation: The IC is tested to verify that it meets its performance and functionality requirements.
Both design verification processes require a team of experienced engineers with expertise in various verification tools and techniques. By using DFT ATPG, LEC, sign-off, and post-silicon validation, the design verification process ensures that the IC is reliable, testable, and meets all the requirements. The design verification process helps to identify and fix any errors or bugs in the design before the IC is fabricated, saving time and costs.
