Abstract:
A software-based system used for simulating the combined functionality of a South Bridge test module and a North Bridge test module, comprising:a South Bridge chipset used for simulating the functionality of a PCI-to-ISA bridge controller; a PCI master modeling circuit coupled via a PCI bus to the South Bridge chipset, which can simulate the functionality of a PCI master unit, and can process a North-Bridge-specific set of input/output signals; a PCI slave modeling circuit coupled via the PCI bus to the South Bridge chipset, which can simulate the functionality of a PCI slave unit, and can deliver a wait state for simulating the delay in the memory access operation in a North Bridge chipset, and can further perform a retry-count function for simulating the effect of delayed transaction in the North Bridge chipset; and a PCI arbitrator simulation circuit coupled via the PCI bus to the South Bridge chipset, which can simulate the functionality of a PCI arbitrator.
