Convert UPF to CDB

Understanding UPF and CDB file formats

UPF (Unified Power Format) is a standard file format used in electronic design automation (EDA) to describe power intent in integrated circuit (IC) designs. It helps define power domains, power states, and power management strategies for complex chips, ensuring efficient power usage and management during the design process.

CDB (Cadence Database) is a proprietary file format used by Cadence Design Systems' EDA tools. It stores design data, including layout, schematic, and other information necessary for IC design and verification. The CDB format is essential for workflows within the Cadence Virtuoso platform and related tools.

Why convert UPF to CDB?

Converting a UPF file to a CDB file is typically required when integrating power intent information into a Cadence-based IC design flow. This allows designers to ensure that power management strategies defined in UPF are accurately reflected in the Cadence design database for further simulation, verification, and implementation.

How to convert UPF to CDB

There is no direct, standalone converter for UPF to CDB, as the conversion is usually handled within the EDA toolchain. The process involves importing the UPF file into a Cadence environment and then saving or exporting the design, including the power intent, into the CDB format. Here’s how you can do it using Cadence tools:

• Open your design in Cadence Innovus or Virtuoso.
• Import the UPF file using the tool's power intent import feature. This is typically done via the command line or a GUI option such as File → Import → Power Intent (UPF).
• Verify that the power domains and constraints from the UPF file are correctly integrated into your design.
• Save the design. The tool will store the updated design, including the power intent, in the CDB format.

Best software for UPF to CDB conversion

The most reliable and industry-standard software for this conversion is Cadence Virtuoso or Cadence Innovus. These tools natively support UPF import and manage the design database in CDB format, ensuring seamless integration and accurate conversion.

Summary

To convert UPF to CDB, use Cadence EDA tools to import the UPF file and save the design in CDB format. This ensures that your power intent is preserved and integrated into your IC design workflow.
