Called Certus closure solution, the “environment automates and accelerates the complete design closure cycle, from sign-off optimisation through routing, static timing analysis and extraction”, said Cadence. “The solution supports the largest chip design projects with unlimited capacity.”
It lists these attributes:
- Distributed hierarchical optimisation and sign-off architecture for cloud and internal data centre environments
- Incremental sign-off allows restore and replacement of only the changed portions of the design
- Automated flow
- Interactive GUI (SmartHub interface) allows cross-probing for detailed timing debug
- Integrated with Integrity 3D-IC for closing inter-die paths between heterogenous die
“Prior to the introduction of the Certus closure solution, a full-chip closure flow involved manual processes from full chip assembly, static timing analysis, and optimisation and sign-off with 100s of views,” according to the company. “The new solution provides a fully automated environment that is massively distributed for superior optimisation and sign-off. This allows concurrent, full-chip optimisation through an engine shared with the Innovus implementation system and the Tempus timing sign-off solution.”
