8.1. Simulation Options
- Full calibration—Calibrates the same way as in hardware, and includes all phase, delay sweeps, and centering on every data bit.
- Quick calibration—Calibrates the read and write latency only, skipping per bit deskew.
- Skip calibration—Provides the fastest simulation. It loads the settings calculated from the memory configuration and enters user mode.
By default, the UniPHY IP generates abstract PHY, which uses skip calibration regardless of the simulation options that you chose in the parameter editor.
The following table lists typical simulation times implemented using UniPHY IP. The simulation times in the table are estimates based on average run times of a few example designs. The simulation times for your design may vary depending on the memory interface specifications, simulator, or the system you are using.
