Conformal ECO Designer

15 Sep 2024 • 1 minute read

Conformal ECO Designer enables you to implement RTL engineering change orders (ECOs) for pre- and post-mask layout and offers early ECO prototyping capabilities for driving critical project decisions.

Conformal ECO compares two designs and generates a functional patch that implements the changes between the two designs.

One major criterion for determining patch quality is whether the patch can meet timing closure. To determine this, you typically need to run the time-consuming process of incremental synthesis and place-and-route. Instead, Conformal can analyze path logic depth changes before and after ECO patch generation. This provides a faster way to evaluate timing impact in patch generation stages.

After the patch is created and applied, it is passed to Genus to optimize the patch.

During patch optimization, you can choose to do many things like:

  • Keeping constants in the patch
  • Allowing tie cell inversion
  • Specifying tie cell types
  • Preserve DFF cells and cell types in the patch
  • Preserve all cells and nets in the patch
  • Preserve clock buffer cell in the patch
  • Turn on/off sequential constant and sequential merge in patch optimization
  • Allowing phase mapping for DFFs
  • Map to spare cells
  • Force fix DRC before timing

What's Next?

Join the Conformal ECO course to:

  • Explore the many options and capabilities of Conformal ECO
  • Use Conformal Engineering Change Order (ECO) for flat and hierarchical designs
  • Generate a functional ECO patch, apply it to a design, optimize it, and map it to a specified technology
  • Run a hierarchical design through ECO and run a comparison to prove the ECO is equivalent
  • Run a postmask ECO using Conformal ECO GXL

Make sure you have experience with Conformal Equivalence Checker or completed the Conformal Equivalence Checking course before taking this course.
