Design Flow

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

Analog Design Task Design Tools Used Output => Mixed-Signal Chip/Core Task
 
 
Systems Modeling MathCAD, MatLab M-S Placeholder Behavioral Model => Digital HDL
Schematic Entry Cadence Composer  
Circuit Simulation Cadence Spectre M-S Block Synthesis Model => Digital Logic Synthesis
System Simulation Cadence SpectreHDL Accurate M-S Behavioral Model => Analog Integration
  Mixed-Signal Simulation
Physical Implementation Cadence Virtuoso M-S Physical Outline => Core/Chip Place & Route
Parasitic Extraction Cadence Assura  
Physical Verification Cadence Assura & Spectre M-S Physical Layout GDS-II => Merge Circuit Layouts
  Analog Refinement
  Tape-out to Samples
Design Validation Lab Evaluation Characterization => Performance Validation
