参考下emi_handbook, v4, chapter 3 吧。 calibration 要做很多事情。。
-----------------------------------------------------------------------------
The ALTMEMPHY IP performs the following calibration stages:
1. Enter Calibration (s_reset)
2. Initialize PHY (s_phy_initialize)
3. Initialize DRAM
4. Write Header Information in the internal RAM (s_write_ihi)
5. Load Training Patterns
6. Test More Pattern Writes
7. Calibrate Read Resynchronization Phase
8. Advertize Write Latency (s_was)
9. Calculate Read Latency (s_adv_rlat)
10. Output Write Latency (s_adv_wlat)
11. Calibrate Postamble (s_poa)
12. Set Up Address and Command Clock Cycle
13. Write User Mode Register Settings (s_prep_customer_mr_setup)
14. Voltage and Temperature Tracking

。您是怎么对自己的ddr2控制器进行仿真的呢，如果能有相应的testbench参考代码就更好啦，希望能不吝赐教。谢谢！
