Company Overview
Z Circuit is a privately-held company based in Mountain View, California, USA and includes both domestic and international sales channels.
Why Choose Z Circuit
The accuracy of the cell library models you use for your designs is critical to achieving working silicon in a timely fashion. As feature sizes have gone down, digital cell models have become increasingly complex. Z Circuit software employs unique model generation methods for highly accurate models that are especially critical for the more complex cells in a library.
If you need to produce new models, validate your existing models, or re-design circuits to achieve high speed or low power, Z Circuit has tools that can help.
ZChar Library Characterization
- Achieve highly accurate models to maximize your chance for working silicon and high yield
- Re-characterize an existing library to new process, voltage, or temperature corners
- Characterize new cells, including very complex cells, for an existing library
- Characterize special cells such as DDR and IO Pads that many tools cannot handle correctly
- Get results quickly
ZChar Memory Characterization
- Quickly create instance-based memory models using a highly parallel multi-simulation flow
- Characterize either custom or generated memories
- Produced dramatically reduced netlists for ultra fast and accurate simulations
- Achieve highly accurate timing and power models including unique worst-case path selection
Z Circuit Library Analyzer
- Validate the accuracy of an existing library
- Validate the consistency between library corners
- Compare against a prior release or a different library
- Analyze cells in a library for performance
First-class Support
Z Circuit is a team of cell characterization specialist with extensive experience in digital design flow and cell library requirements. When you work with Z Circuit, you get access to both leading-edge software and an experienced technical support team. Library characterization requires unique expertise in both circuit design and digital design. Many EDA companies do not provide this mix of expertise for their cell characterization products.
