1. Added testbench for SOPC Builder example. Need to fully implement the self-check test cases. Just ignore the reported failures, and check the waveform for correct addressing.
2. Added GENERATE BLOCK for top-level addr_in unit selection. In normal top-level instantiation without modify the default addr_is_in_word = 0 parameter, the default address unit is in byte (8bit); When instantiated in SOPC Builder, the address unit is default to word (32bit). |

1. Redefined the memory map. See changes in reg.v and ptp_drv_bfm.c.
2. Added adj_done signal for CPU polling.
3. Making time_acc_modulo a constant = 256,000,000,000. No need to change it from software side. |
