Detailed Description

Abstract interface for wishbone transactions, used by ~all classes in pflib.

This defines the necessary functions that communications methods need to implement.

Member Function Documentation

◆ wb_clear_counters()

virtual void pflib::WishboneInterface::wb_clear_counters ( )

pure virtual

Clear the monitoring counters.

Implemented in pflib::rogue::RogueWishboneInterface, and pflib::uhal::uhalWishboneInterface.

◆ wb_errors()

virtual void pflib::WishboneInterface::wb_errors	(	uint32_t &	crcup_errors,
		uint32_t &	crcdn_errors,
		uint32_t &	wb_errors
	)

pure virtual

Read the monitoring counters crcup_errors – CRC errors observed on the uplink (wraps) crcdn_errors – CRC errors from the downlink reported on the uplink (wraps) wb_errors – Wishbone errors indicated by the Polarfire.

Implemented in pflib::rogue::RogueWishboneInterface, and pflib::uhal::uhalWishboneInterface.
