Format –
Example –
This command enables a predefined trace type. Run-time traces
generate text output representing the state of the architecture on a cycle-
by-cycle basis. There are four types of predefined runtime tracing:

enable break breakpoint_number
zsim{32} enable break 1
du
Displays information from the data unit of the ZSP400 architecture,
such as data cache hits and the du_imem_read signal. This is not
valid for G2.
iu
Displays information from the instruction unit, such as instruction
cache hits and instruction fetch signal.
For zsim400, the output looks like:
cycle# -
cycle# -
For zsimg2, the output looks like:
The first column displays the cycle count. The PFU_COND line displays
the condition of the PFU state machine and the mode it operates in.
The possible states are shown in
cond_abort_mode=1 means the PFU receives the reqi_cond_abort
signal from the memory subsystem. The PFU_PC line displays the
current PC address coming from the ISU (Instruction Sequencing
Unit). The PFU_AGN line displays agn status for the loop awakening
logic. The next line shows the state of the cl_unv (cache-line
unavailable) and cl_disc_unv (cache-line discontinuity unavailable)
IU_IMEM_READ : address
