# Using AI to edit Cadence Projects A handheld-computer engineer updates an OrCAD and Allegro design with an in-stock ICM-45686 IMU and checks its lid clearance.

After an acquisition, the team lost its OrCAD and Allegro seats. Now the MPU6050 at U57 is end of life, and the replacement must use the same I²C bus. ## The problem Sam needs the new IMU in the schematic and PCB, with its support parts and signal path in the design. > "The MPU6050 (U57) is end of life and we can't buy it anymore. Find an in-stock replacement IMU, swap it in the schematic and on the PCB, keep it on the same I2C bus, and update any support parts it needs. Then tell me what changed." ## Three steps in the project 1. **Choose:** Flux selected ICM-45686 for U57. 2. **Update:** The schematic and PCB now show the new IMU and updated support parts. Its supply, SDA, SCL, and interrupt connections remain in the board design. 3. **Check height:** The new part has 5.1 mm of reported clearance below the 6 mm lid. ![Cadence PCB layout centered on the ICM-45686 replacement at U57.](https://www.flux.ai/p/assets/blogs/using-ai-to-edit-cadence-projects/layout.webp) U57 and its local board context. The 5.1 mm measurement gives Sam a specific value for the new component. The project keeps the part change and the enclosure-height result together.
