1.13. Freeze Logic for 28-nm PR Regions
Freezing prevents the signal receivers in the static region from receiving undefined signals during the partial reconfiguration process. Freezing is important for control signals that you drive from the PR region. Cyclone® V or Stratix® V devices require that you freeze global and non-global inputs of a PR region.
The static region logic must be independent of all the outputs from the PR regions for a continuous operation. Control the outputs of the PR regions by creating an RTL wrapper around the PR region.
