The migration of circuit schematics between different process technologies and process design kits (PDKs) can be a very time-consuming, uncomfortable and boring task for a circuit designer.
At the beginning of – or during – a new design project, it is often necessary to use and re-use available IP (intellectual property) and circuits from previous projects, instead of designing everything from scratch. Often a new design uses a new or different process technology. Thus, it is necessary to migrate and apply given circuit schematics for use with this new target technology. Consequently, circuit designers very often must adapt schematics to the new process by changing circuit symbols, default values, scaling and other characteristics – a time-consuming and tedious manual effort.
3-Step Schematic Porting, Assessment & Sizing Flow
When retargeting circuit designs from a given source process to a new process, the source design schematics are adapted primarily using a 3-step flow.
- Schematics are ported and migrated to the new target process using the models and PDK/CDF from the target process technology. This task is very often done manually, but can be automated easily.
- After migration of all such schematics, the circuit designer assesses the ported IP and adapts the circuit topologies – when necessary – in schematic view.
- Based on updates of the circuit specifications, the designer analyzes and re-sizes the circuits (for example, with other MunEDA WiCkeDTM tools) and verifies results such as circuit functionality, performance, yield, and robustness (for example, with simulation such as SPICE).
These steps also can include iterations where necessary.

Datasheet
WiCkeD SPT
The task of schematic porting now can be automated and easily accelerated by using the SPT schematic porting tool, part of MunEDA WiCkeD design tool suite. MunEDA SPT supports designers with an automated schematic migration, replacing cells with corresponding cells in the new library. The tool:
- Replaces devices in the schematic with their counterpart (source PDK to target PDK)
- Provides flexible property mapping and automated shrinking, is configurable, and can handle MOS, R, C, and other properties
- Walks hierarchically through the schematics
