Greyrock Technology leverages the Cadence Design Systems tool flow end-to-end for maximum capability and design efficiency. We're also experienced with other design flows, such as Synopsys and Mentor Graphics, and point tools such as HSpice, and can interface with most design flows.

The Greyrock Technology design flow and interaction with a higher-level core or chip design flow proceeds like this
