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..
我只有把synth_full改C2H執行..

) [) {+ Y) l: ^5 X* C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..
( h# F2 P& U$ k$ O6 ]5 s; \3 x所以要把dct32也用成C2H嗎..
6 Z; `" r& C% a4 {( |8 I4 t$ D我把dct32也用成C2H後這行就不見了..
. u1 A; U. f8 C9 h- f但是其他都還在捏 >"<
還有以下這些是要幹嘛的？
2 p; T  l' d. G. ~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
. i4 K6 S' p$ aidentified subroutine named mad_synth_mute
identified subroutine named dct32
! y  W  E7 k. {0 S9 widentified subroutine named synth_full
identified subroutine named synth_half

* n, H2 H0 b9 @; r==========================================================================
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？
6 {4 n; _9 U/ r" l: |6 }是因為哪裡沒有用好導致C2H不能成功呀!?
