CNTVIRQ[0-3]SignalmasterVirtual timer event
acp_sPVBusslaveAdvanced eXtensible Interface (AXI™) ACP slave port
cfgend[0-3]SignalslaveInitialize to BE8 endianness after a reset.
cfgsdisableSignalslaveDisable write access to some Generic Interrupt Controller (GIC) registers.
clk_inClockSignalslaveMain processor clock input.
clusteridValueslaveSets the value in the CLUSTERID field (bits[11:8]) of the MPIDR.
cntvaluebPrivateslaveSynchronous counter value. This must be connected to the MemoryMappedCounterModule component.
cpuporeset[0-3]SignalslavePower on reset. Initializes all the processor logic, including the NEON and VFP logic, Debug, PTM, breakpoint and watchpoint logic in the processor CLK domain.
cp15sdisable[0-3]SignalslaveDisable write access to some secure cp15 registers.
eventSignalpeerEvent input and output for wakeup from WFE. This port amalgamates the EVENTI and EVENT0 signals that are present on hardware.

presetdbgSignalslaveInitializes the shared debug APB, Cross Trigger Interface (CTI), andCross Trigger Matrix (CTM) logic.
pvbus_m0PVBusmasterAXI bus master channel.
reset[0-3]SignalslaveIndividual processor reset signal.
standbywfe[0-3]SignalmasterIndicates if a processor is in Wait For Event (WFE) state.
standbywfi[0-3]SignalmasterIndicates if a processor is in Wait For Interrupt (WFI) state.
teinit[0-3]SignalslaveInitialize to take exceptions in T32 state after a reset.
ticks[0-3]InstructionCountmasterProcessor instruction count for visualization.
vfiq[0-3]SignalslaveProcessor virtual FIQ signal input.
vinithi[0-3]SignalslaveInitialize with high vectors enabled after a reset.
virq[0-3]SignalslaveProcessor virtual IRQ signal input.
