There are three MPT flows, which are differentiated based on foundry requirements.
- Fully Colored Flow: The layout should have only colored and locked shapes. The layout team is responsible for meeting this requirement.
- Partially Colored Flow: Only critical nets and shapes should be colored and locked to ensure electrical performance and predictability. The remaining shapes can be unlocked or gray as the foundry is responsible for the final coloring of shapes.
- Lockless Flow: Like the fully colored flow, all shapes should be colored but the foundry does not require all shapes to be locked.
The SKILL functions related to the MPT flows are mptCheckFlow(), mptDefineFlow(), mptGetFlowNames(), mptGetFlowSettings(), and mptSetFlow().
