NEXUS.SmartTrace

Format:

NEXUS.Spen<messagetype>

Format:

Configures the core to suppress one or more message types (WTM, PTM, DTM and OTM) when the on-

chip NEXUS message FIFO reaches a certain fill level. Enabling one of these options will in most cases

cause problems in trace analysis, because the trace message stream contains no information about if and

when messages have been suppressed. The fill level at which message suppression occurs can be

configured via the command

NOTE:

Format:

Stall the program execution whenever the on-chip NEXUS-FIFO threatens to overflow. If this option is

enabled, the NEXUS port controller will stop the core's execution pipeline until all messaged in the on-chip

NEXUS FIFO are sent. Enabling this command will affect (delay) the instruction execution timing of the CPU.

This system option, which is a representation of a feature of the processor, will remarkably reduce the

amount FIFO OVERFLOW errors, but can not avoid them completely.

For processors which implement the IEEE-ISTO 5001-2008 or later, STALL can be configured to occur at

several fill levels, while processors which implement an older standard have a fixed level.
