Abstract

An integrated circuit device includes a first partition and a second partition. The integrated circuit device also includes a Joint Test Action Group (JTAG) system that controls at least a portion of the integrated circuit device via logic signals. The JTAG system includes a JTAG interface that receives logic signals and a first JTAG hub instantiated in the first partition communicatively coupled to the JTAG interface. The integrated circuit device further includes a second JTAG hub instantiated in the second partition communicatively coupled to the first JTAG hub via a bridge.
