The following debug read access functions have the same semantics as in CADI, but the values
returned by these read access functions may differ from the values returned by the
corresponding CADI functions because some of the accessed resources values might change
over time during the execution of an instruction. The values of resources that are modified by
the current instruction are UNKNOWN, except the PC which always reflects the address of the
last instruction that was issued. Reading and writing registers and memory while the simulation
is running is generally only useful for syncLevel >= SL_SYNC_STATE. For SL_OFF, all registers
and all memory locations are always UNKNOWN while the simulation is running.
• CADIRegRead()
• CADIMemRead()
• CADIGetParameterValues()
• CADIGetInstructionCount()
• CADIGetPC()
• CADIGetDisassembler()
The following write access functions always provide write access to the register in the
Simulation register group. They also might provide limited write access semantics to certain
resources. A SCADI implementation might choose not to support any write access to core
registers and memory:
• CADIRegWrite()
• CADIMemWrite()
• CADISetParameters()
The breakpoint functions have nearly all the same semantics as in the CADI interface, except
that changes to breakpoints only become effective at the next Stop event checkpoint defined by
the current syncLevel. Changes might also only become visible in CADIBptRead() and
CADIBptGetList() at this next synchronization point.
• CADIBptGetList()
• CADIBptRead()
• CADIBptSet()
• CADIBptClear()
• CADIBptConfigure()
Execution control is limited to stopping the simulation. The simulation stops at the next
synchronization point as defined by the current syncLevel:
• CADIExecStop()
All other functions are not supported, and return CADI_STATUS_CmdNotSupported.
