Table 1 Characteristics of different transceiver simulation models.
From: Simulation and Emulation of MIMO Wireless Baseband Transceivers
| Model/Platform | Characteristics |
Scope (used for  )
|
|---|---|---|
| Floating-point/SW Simulation | Fast (runtime) | Algorithm development |
| Far from hardware (HW) (data and control path) | Reference for other models | |
| Fixed-point/SW Simulation | Slow (runtime) | Golden model for HDL |
| Same data path as HW | Debug data path | |
| Different control path | ||
| Not cycle-true | ||
| HDL/Simulator | Slow (runtime) | Debug control path |
| Data and control path as in final ASIC | Cycle-accurate: determine latencies | |
| HDL/FPGA | Fast (runtime) | Performance, fixed-point characterization |
| Accelerated HDL simulation | Large coverage of functional runs | |
| Regression runs |
