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

In this recent Training Webinar, we explore the concepts of RTL design, design verification, and coverage analysis while unveiling the exciting world of front-end design flow by guiding you through essential steps involved in creating integrated circuits—the building blocks of modern electronics.

We’ll break down the process into manageable stages, from defining the chip’s functionality to its physical realization. We’ll investigate the front-end part of the RTL-to-GDSII flow—from specification to functional verification and design coverage—and explore:

• Key concepts of specifying chip behavior and performance
• How to translate ideas into a digital blueprint and transform that into a design
• How to ensure your design is free of errors
