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..
( R5 S' t& c$ ?# [) j我只有把synth_full改C2H執行..

請問一下各位大大...
; j1 F" D  f: w6 k! p- s9 Q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..
所以要把dct32也用成C2H嗎..
我把dct32也用成C2H後這行就不見了..
% e( p8 z% m, g% _7 p1 k# z# a但是其他都還在捏 >"<
還有以下這些是要幹嘛的？
  U. \/ s* Y7 d6 |% K6 z( o% a2 n只是說這一個C檔裡有這些副函式而已嗎??
還是有關C2H不能編譯過的關鍵呢？
identified subroutine named mad_synth_init
& k8 P$ g, Y: Qidentified subroutine named mad_synth_mute
0 G# w, u* k; R$ ^% Q1 X% ^identified subroutine named dct32

2 ?* `3 g0 x* ~6 D7 I1 I9 S最後這行我覺得應該是C2H不能成功的最大問題！
% t8 U# P+ h  x: I  p4 N2 m6 omaking hdl for subroutine named dct32
這問是什麼意思呢？
2 R% q* l4 m; K* n$ V3 d* |& [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~~
非常感謝喔
