Carbon GIC PL390 Model User Guide for SoC Designer Plus

1-6 Using the Model Kit Component in SoC Designer Plus1.3 Available Component ESL PortsTable 1-2 describes the PL390 ESL ports that are exposed in SoC Designer Plus when youhave defined an AHB-Lite component. See the ARM PrimeCell® Generic Interrupt Controller(PL390) Technical Reference Manual for more information.Each AHB-Lite or AXI signal uses a suffix to identify the interface; either d for Distributoror c for CPU interface.Table 1-2 AHB-Lite ESL Component PortsESL Port Description Direction Typeahb_c AHB-Lite slave for the CPU interface. Input Transaction slaveahb_d AHB-Lite slave for the distributor. Input Transaction slavegresetReset for the GIC. This signal is active HIGH Input Signal slaveby default.legacy_irq_c0 Legacy IRQ interrupt for CPU interface. Availableonly if legacy has been configured. Activehigh/low is controlled by the negLogicparameter. This signal is active HIGH bydefault.Input Signal slavespi Shared peripheral interrupt inputs. Input Signal slaveclk-in Clock slave port. Input Clock slaveirq_c0IRQ interrupt for the processor that connects tothe CPU interface. Active high/low is controlledby the negLogic parameter. This signalis active HIGH by default.Output Signal masterTable 1-3 describes the PL390 ESL ports that are exposed in SoC Designer Plus when youhave defined an AXI component. This configuration supports security extensions and cancontain up to 8 CPU interfaces. Some other ports appear only when the GIC has been configuredwith certain functionality in AMBA Designer.Table 1-3 AXI ESL Component PortsESL Port Description Direction Typeaxi_c AXI slave for the CPU interface. Input Transaction slaveaxi_d AXI slave for the distributor. Input Transaction slaveenable_c 1 Provides a mask select to access registers in aCPU interface. Available only if more thanone processor has been configured.Input Signal slaveenable_d 1gresetProvides a mask select to access banked registersin the Distributor. Available only if morethan one processor has been configured.Reset for the GIC. This signal is active HIGHby default.InputInputSignal slaveSignal slaveCarbon Design Systems, Inc. Confidential
