各位大牛，請教個問題，我在做postsim的時候出現下列訊息：

下面是我引用sdf時的command：請問一下我是那邊出錯了嗎？
sdf檔案在檔案C:/Modeltech_5.7f/examples/interleaver/interleaver_postsim下
initial
begin
  $sdf_annotate("C:\Modeltech_5.7f\examples\interleaver\interleaver_postsim\interleaver_timesim.sdf",interleaver_tb);
end

将$sdf_annotate(“”，...)中的每一个'\'都用'\\'替代试一试。

厲害厲害～～
我真的只有一聲嘆息了!!!!
真是非常感謝啦^^

在請問一下，改了之後出現這個問題～～

可不可以在麻煩幫忙一下～～@@

一声叹息 · 发表于 2003-12-9 17:11:16

是不是SDF的作用范围不对？该SDF是作用到interleaver_tb还是应该作用到interleaver?

yaolung · 发表于 2003-12-9 19:17:14

之前改的用來作interleaver_tb的postsim可以模擬，結果也正確，我照原法改另一個project的testbench : map_decoer_1_timesim.sdf 就出現了上面的錯誤～
我是不曉得從那邊看sdf對應到那個文件，下面是我在testbench中的寫法，
initial
begin
$sdf_annotate("C:\Modeltech_5.7f\examples\interleaver\interleaver_postsim\interleaver_timesim.sdf",interleaver_tb);
end
感覺像是對應到map_decoer1_posttb ???

一声叹息 · 发表于 2003-12-9 21:45:44

最大的可能是读取的sdf文件与你指定的标注实例（instantiation）不符。
$sdf_annotate("C:\\Modeltech_5.7f\\examples\\mapdecoder_postsim\\map_decoer_1_timesim.sdf",map_decode_1_instantiation);

yaolung · 发表于 2003-12-10 01:22:47

标注实例（instantiation）是指我的top module還是testbench~
我是寫testbench : map_decoder1_posttb
這樣對吧～～？？
$sdf_annotate("C:\Modeltech_5.7f\examples\mapdecoder_postsim\map_decoer_1_timesim.sdf",map_decoder1_posttb );

一声叹息 · 发表于 2003-12-10 08:32:23

我觉得应该是你的top module

yaolung · 发表于 2003-12-10 22:41:34

我後來TRY了一下，寫法是沒錯啦(topmodule_tb)，因為我用別的project來作，結果相同的步驟，別的project可以作後仿真，但是map_decoder_1這個就不行@@

真的想不到還有哪裡有問題，沒辦法只好在從頭在試一遍看看囉@@
