如果以上問題你都有嘗試過,那的確很高機率是你的Bram Module接腳上的Wishbone沒正確接上,你可能要再研究一下Bram是否有正確時間並正確收到資料,你如果怕FIR.C寫的是錯的,也可以透過隨便在FIR.C寫Outputsignal的值,應該Bram如果有正常收到資料,值都會跑出來。 |

要搭配 waveform 來看問題。 |

已查看先前問題包括移除#include <stub.c>、user_proj的問題,
想詢問lab4-1中user_proj是否只要寫出bram讀取的延遲(10+2cycle)硬體?
我對此lab的理解為寫完fir.c後他會結合counter_la_fir.c,
在一開始先寫入0xAB400000此address,並在寫入後讀取hex後做為checkbit,
之後的資料來自於fir.c中的outputsignal,一併寫入hex,
最後再寫入0xAB510000同第一步寫到hex後做為checkbit,
但從rum_sim來看我連第一個checkbit都沒讀到,
這代表我沒成功將bram的值透過wishbone的介面傳出?
