PowerPC Simulator Target
xmd can connect to one or more PowerPC Instruction Set Simulator (ISS) targets through
socket connection. Use the ppcconnect sim command to start the PowerPC ISS on
localhost , connect to it and start a remote GDB server. ppcconnect sim can also connect to
PowerPC ISS running on localhost or other machine. Once xmd is connected to the
PowerPC target, powerpc-eabi-gdb can connect to the target through xmd and
debugging can proceed.
Running PowerPC ISS
XMD starts the ISS with default configuration. The ISS executable can be found in
${XILINX_EDK}/third_party/bin/<platform>/ directory. The configuration file used is
${XILINX_EDK}/third_party/data/iss405.icf. User can run ISS with different
configuration option and xmd can connect to the ISS target. Refer “ISS User Guide”
document for more details. The following are the default configuration for ISS.
x Two local memory banks: Mem0 start address = 0x0, length = 0x80000 and speed = 0.
Mem1 start address = 0xfff80000, length = 0x80000 and speed = 0.
x Connect to Debugger (xmd)
x Debugger Port at 6470
x Data Cache size of 8k
x Instruction Cache size of 16k
x Non-Deterministic Multiply cycles
x Processor Clock Period and Timer Clock Period of 5ns (200 Mhz)
