Abstract: The embodiments described herein may improve utilization of an emulator system's resources, and may improve efficiency and effectiveness in bug-identification and/or target-debugging; the components described herein may improve utilization of the emulator's resources, reduce wait time to execute emulation routines, and may limit or eliminate the need to stop or kill emulations in process. The various embodiments described herein allow for dynamically associating domains and targets by dynamically allocating and assigning domains with particular target connections, which are pins and/or wires that connect target pods to the emulation system. An emulation system may comprise one or more target MUXs that are situated between the target connections and the domains, to allow the relationships between target pods and domains to be identified and switched dynamically. The target MUXs may be reprogrammed while emulations are ongoing, in order to redirect data communications between available domains and target pods of target systems.
