I was working on smart wearable using ARM Cortex A series so there is any other simulator for ARM CORTEX A
Yes, QEMU.wiki.qemu.org/.../ARM
Sir, I want to make it on ARM CORTEX A-8 Series microprocessor with my own design so there is any way to Connect all modules virtually.
You can get the QEMU sources. Means, you can add all the peripherals you want. Or go for commercial products like SIMICS from WindRiver.
