After the design is complete (placed and routed), VIV is used again on the implemented design to validate that the required isolation was built into the design.
At this step, VIV checks the following:
- VIV analyzes the complete placed and routed design.
- Tile-based isolation analysis looks for a barrier (fence) between isolated
regions.
- A valid user tile acts as a sufficient isolation barrier if:
- It does not contain any isolated signals (from any isolated region).
- It is configured in the default (unused) state.
- A valid user tile acts as a sufficient isolation barrier if:
- VIV does the same pin and I/O checking as in Floorplan mode.
