1. An integrated circuit, comprising:
a static region;
a first partial reconfiguration (PR) sandbox region configured using a first tenant workload;
a second partial reconfiguration (PR) sandbox region configured using a second tenant workload; and
a secure device management (SDM) circuit configured to:
validate one or more configuration bitstreams comprising the first and second tenant workloads at the integrated circuit during runtime; and
provide spatial isolation between the first and second PR sandbox regions by preventing the first and second tenant workloads from interfering with each other.
