Full Chip Migration

The migration of analog and mixed signal chips gives fabless companies and IDMs the opportunity to find second sources of their products or reduce maufacturing costs by moving to a new process or foundry.  The difficulty of recreating circuits in a new process means that most companies fail to take advantage of the opportunities offered by alternative manufacturing and miss out on opportunties to revitalise products and reduce costs.

Full chip migration can be completed using a GDSII file and a netlist or from a full Cadence database.  Active and passive components are mapped to the new process and complex components including radio inductors, I/O and ESD are converted to the new proces requirements.  OSIRIS technology delivers a flexible and structured approach which brings automation to the majority of the circuit and still allows detailed editing of critical areas of the circuit.

Whether for cost reduction, second source or to replace a current foundry, transferring a chip with OSIRIS migration technology can move complete products between foundries and processes.

The Challenge of Full Chip Migration

Moving older chips between foundries can also present problems when the original design team is not available.  A lack of detailed circuit knowledge can mean engineers are reluctant to transfer the circuit to a new process for fear of harming performance or functionality.

OSIRIS is designed to make minimal changes in circuit layout to retain circuit integrity.  Automatic topology matching ensures that performance is maintained by preserving critical component and routing placement, maintaining a balance of parasitic loads.

OSIRIS technology delivers flexible and structured approach which allows the design to be ported rapidly, retaining critical elements and structures while giving options to use foundry components such as I/O cells direct from the target process.
