NEXUS.SmartTrace
Enable smart trace analysis
NEXUS.Spen<messagetype>
Enable message suppression
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
NEXUS.STALL
Stall the program execution when FIFO full
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.
