The Endpoint model consists of these blocks:
- PCI Express Endpoint (the core in Endpoint configuration) model.
- PIO slave design, consisting of:
-
PIO_RX_ENGINE -
PIO_TX_ENGINE -
PIO_EP_MEM -
PIO_TO_CTRL
-
The PIO_RX_ENGINE and PIO_TX_ENGINE blocks interface
with the Endpoint block for reception and transmission of TLPs from/to the Root Port
Design Under Test (DUT). The Root Port DUT consists of the core configured as a Root
Port and the Configurator Example Design, which consists of a Configurator block and a
PIO Master design, or customer design.
The PIO slave design is described in detail in Programmed Input/Output: Endpoint Example Design.
