看文献头大了，盯着这两段看了半天，呵呵，谁帮我指点一下吧，

DBI model sends commands and data packets as dictated by dbi_cmd.v  .The data to be sent by the DBI model is placed in dbi_send.dat, gen_bs_send,dat, gen_lp_send.dat. for DBI, generic high speed and low power data transfers respectively.

in all the DBI models, data packetsto be received are collected from the DSI receiver model and stored in buffers, for read transfers, the received data is checked with the previously collected data in buffer.

这两段讲的是不同的环境下的吧，第一段讲在仿真情况下，数据的发送来自三个dat文件，第二段讲真实情况下，数据从DSI receiver接收，然后干嘛和之前的数据check啊？
