Secure Your PCB Intellectual Property with Database Locking in OrCAD X Presto

vidhyaparameswari

Collaborating on PCB designs often requires sharing database files with customers, partners, or manufacturing teams. OrCAD X Presto's IP Protection Locking feature helps safeguard sensitive design information by allowing designers to control how a database can be viewed, modified, saved, or exported after it is shared.

  1. Open your design and navigate to File → IP Protection Locking to access the database protection options. 

  2. Enable Lock Design and enter a secure password to protect the database from unauthorized modifications. Passwords are case-sensitive and support up to 20 alphanumeric characters. 

  3. Optionally define an Expiration Duration to automatically limit how long the lock remains active. 

  4. Select the appropriate lock mode based on your sharing requirements:

    • View Lock to prevent saving and exporting.
    • Export Lock to restrict exports of protected data.
    • Write Lock to prevent database saves while allowing exports. 

  5. For enhanced security, enable NTP Time Verification and specify an NTP server to ensure lock expiration is validated against a trusted time source. 

  6. Confirm the password and click OK to create a locked copy of the design. A new database file is generated with a lock-specific suffix while the original design remains unchanged. Users opening the locked database can only perform actions permitted by the selected lock mode. 

  7. Recipients can open the design but will receive warnings when attempting restricted actions. 

Bulb Pro Tip: Keep a secure record of the password. Locked databases cannot be recovered if the password is forgotten.
