詢問一下C2H的錯誤訊息意思

static314

以下是我執行NIOS II執行C2H的ERROR訊息..
8 @! |0 ?! M6 C7 }我只有把synth_full改C2H執行..

請問一下各位大大...
上面的錯誤訊息是什麼意思呀!?
synth_full calls dct32 意思是說有呼叫到dct32..
5 w" c& O) W4 }8 e5 u  ^$ l所以要把dct32也用成C2H嗎..
/ f5 B# K' a. N. V8 d- ~3 R$ p/ ^* k我把dct32也用成C2H後這行就不見了..
但是其他都還在捏 >"<
還有以下這些是要幹嘛的？
只是說這一個C檔裡有這些副函式而已嗎??
, z! U" V2 A1 e4 v' `4 P# j* k還是有關C2H不能編譯過的關鍵呢？
% K, A: |( ~6 K; q4 j9 L6 Lidentified subroutine named mad_synth_init

6 x  ^+ Z& b- r) O7 X# Bidentified subroutine named mad_synth_frame
==========================================================================
最後這行我覺得應該是C2H不能成功的最大問題！
making hdl for subroutine named dct32
這問是什麼意思呢？
是因為哪裡沒有用好導致C2H不能成功呀!?
卡好多天了..一直找不到相關的資料
請各位大大幫忙一下呀~~
