Chapter 4: Create/Import Peripheral Wizard

Select Bus Interface

In this panel you indicate the CoreConnect bus-interface, i.e. if your peripheral is a fast (but

more complicated) PLB (Processor Local Bus) or a comparatively simpler and slower OPB

(on-chip peripheral bus) peripheral. For the present, only slave type peripherals are

supported. Master type peripherals will be supported in a future release.

Select IPIF Services

All user peripheral templates created with this tool incorporate a module called the IPIF

(for Intellectual-property interface.) There are two kinds of IPIFs: PLB and OPB. One side

of this interface implements the PLB or OPB interface, and the other side implements the

IPIC (intellectual-property interconnect) interface. The user peripheral implements the

IPIC. The IPIC is bus agnostic, hence it is possible to create user modules with a IPIC

interface that can operate on both a PLB or OPB. Additionally, the IPIC is ‘hardware

friendly’ and thus easier to work with.Table 4-3.
