Tenders Are Invited For Design And Execution Of Research And Development – ​​Layout Services For Analog And ... in France

Work Detail

Design And Execution Of Research And Development – ​​Layout Services For Analog And Mixed Integrated Circuits. The Services Entrusted To The Holder Will Be Analog And Mixed Block Layout Services. These Blocks Will Be Described In The Form Of Annotated Diagrams Available In A Cadence Database When The Task Starts. An Integrated Circuit Database Brings Together All The Diagrams Constituting The Circuit, Organized Hierarchically. The Physical Implementation Of These Diagrams Will Be Done In Several Stages And At Several Granularities. They Can Be Described As Follows: Layout Of A Block Diagram: - Analysis Of The Diagram: O Identification Of Sensitive Points, Topological Constraints, Implementation Precautions To Be Taken O Proposal Of A Floorplan Of The Block And Evaluation Of The Surface - Creation Of The Layout: O Placement And Connection Of The Components O Proposal For Minor Modification Of The Diagram If Relevant - Carrying Out Checks: O Drc O Lvs At The End Of The Layout Stages, Diagram Views Integrating The Parasitic Elements Induced By The Physical Implementation Are Extracted And Simulated By Cea Designers To Validate The Suitability Of The Layout With The Expected Performance. In The Event Of Insufficient Performance, A Rework For Optimization Of The Layout May Be Requested. Layout For Assembling Blocks Together Into Macro-Blocks: The Steps Are Essentially The Same As For Unit Blocks (Analysis, Layout, Verifications), But At A Higher Level Of Hierarchy. The Complexity Of These Assemblies Depends On The Number Of Interface Signals, Various Topological Constraints (Power Supply Constraints, Insulation, Surface Limits, Etc.) Top Assembly Layout: This Involves Carrying Out The Assembly At The Highest Levels Of The Circuit, Between The Pads (Often Organized In A Ring), And The Highest Level Macro-Blocks. This Assembly Is Very Different If The Top Of The Circuit Is Called “Digital” Or “Analog”. The Top Assemblies Considered For The Layout Tasks Will Only Be Analog Tops.
