38.4. Parameters

Generation-time parameters control the features present in the hardware.The table below lists and describes the parameters you can configure.

Table 400.  Parameters for VIC Core
Parameter Legal Values Default Description
Number of interrupts 1 – 32 8 Specifies the number of irq_input interrupt interfaces.
RIL width 1 – 6 4 Specifies the bit width of the requested interrupt level.
Daisy chain enable True / False False Specifies whether or not to include an input interface for daisy chaining VICs together.
Override Default Interrupt Signal Latency True/False False

Allows manual specification of the interrupt signal latency.

Manual Interrupt Signal Latency 2 – 5 2

Specifies the number of cycles it takes to process incoming interrupt signals.

Because multiple VICs can exist in a single system, Platform Designer assigns a unique interrupt controller identification number to each VIC generated.

Keep the following considerations in mind when connecting the core in your Platform Designer system:

  • The CSR access interface (csr_access) connects to a data host port on your processor.
  • The daisy chain input interface (interrupt_controller_in) is only visible when the daisy chain enable option is on.
  • The interrupt controller output interface (interrupt_controller_out) connects either to the EIC port of your processor, or to another VIC’s daisy chain input interface (interrupt_controller_in).
  • For Platform Designer interoperability, the VIC core includes an Avalon® -MM host port. This host interface is not used to access memory or peripherals. Its purpose is to allow peripheral interrupts to connect to the VIC in Platform Designer. The port must be connected to an Avalon® -MM agent to create a valid Platform Designer system. Then at system generation time, the unused host port is removed during optimization. The most simple solution is to connect the host port directly into the CSR access interface (csr_access).
  • Platform Designer automatically connects interrupt sources when instantiating components. When using the provided HAL device driver for the VIC, daisy chaining multiple VICs in a system requires that each interrupt source is connected to exactly one VIC. You need to manually remove any extra connections.
