CodeWarrior for MCU does not include a simulator for ARM. Options are the ones outlined in this thread. Keep in mind that even these similator are mostly core simulator and do not simulate the full device.
I'm aware of the following two:
a simulator is not included in KDS. But there is QEMU which you could use, see The GNU ARM Eclipse QEMU .
I hope this helps,
There is pre-built simulator at that link which can be tried [it takes about 30..40s from clicking the download link to running a virtual FRDM-K64F with Ethernet, Web server, Telenet, SD card and USB (although Winpcap should be installed on the PC due to its DLL being needed - it is already there if Wireshark has been installed].
