| We handle few flavours: |
| - Hardware Emulator AKA HE which is FPGA based chasis |
| - Simulator based on MetaWare nSIM |
| - NPS400 chip based on ASIC |

| Here we add new hierarchy for CPUs topology. |
| We got: |
| Core |
| Thread |
| At the new thread level each CPU represent one HW thread. |
| At highest hierarchy each core contain 16 threads, |
| any of them seem like CPU from Linux point of view. |
| All threads within same core share the execution unit of the |
| core and HW scheduler round robin between them. |
