You can include up to 128 instances of the in-system sources and probes IP core in your design, if your device has available resources. Each instance of the IP core uses a pair of registers per signal for the width of the widest port in the IP core. Additionally, there is some fixed overhead logic to accommodate communication between the IP core instances and the JTAG controller. You can also specify an additional pair of registers per source port for synchronization.
