linux 64位vcs,求助，VCS在ubuntu 64位的问题
我在ubuntu 10.04LTS里面安裝了VCS，啟動VCS和DVE都可以，我編譯verilog文件的時候出現如下錯誤。
我有兩個文件，count.v 和count_tb.v，使用vcs count_tb.v count.v執行有問題。log如下：
/usr/synopsys/D-2010.06-4/bin/vcsMsgReport: line 332: /bin/basename: 沒有那個文件或目錄

這個錯誤可以通過安裝g++-multilib解決，但是連接還是有第二個錯誤，怎么解決呢，log如下：

問題已經解決，哎整了將近兩天啊。
解決方法如下：
執行編譯命令，遇到這個問題后，在當前目錄下會有一個csrc目錄，進入這個目錄，發現有個Makefile，用gedit打開，將下面字段
# Override TARGET_ARCH
TARGET_ARCH=
修改為：
# Override TARGET_ARCH
TARGET_ARCH=x86-64
并且刪除*.o，rm *.o，然后再執行make，重新生成rmapats.o文件，這次生成的就對了。
這也是一種臨時解決辦法，真是折騰啊。
使用vcs -full64 x.v 仍然存在問題，采用類似方法會出現段錯誤，64位使用不了。只能使用32位的了。
=====================================================
= 后來64位的采樣類似的方法處理之后也可以，無語啊無語！方法如下：
=====================================================
正如上面所述，會遇到段錯誤，此時將csrc目錄刪除，rm -r csrc，然后執行下面命令：
vcs -full64 -m64 xx00.v xx01.v xx02.v
正確生成simv文件，模擬正確。
=====================================================
另外：我在安裝comon的時候，安裝到最后出現過錯誤，被我忽略了，不知道有沒有后遺癥。
根據目標目錄下的instll.log可以分析，暫且不管！
高手啊高手
不錯啊，剛好碰到這個問題
我的錯是“/usr/bin/ld: i386:x86-64 architecture of input file `/usr/lib/x86_64-linux-gnu/crti.o' is incompatible with i386 output”
這個怎么搞定?我原來跑得好好的，都不知道裝那個東西搞爛的 T_T
跟Linux沒啥關系吧
good man
應該是前后兩次編譯的版本之類的有問題吧?
我也遇到同樣的問題，依照樓主的解法已經解決了，
最後我是用 vcs -full64 -m64 xxx.v 解決的，
感謝樓主
vcs開關不對，具體怎么操作我也不是很清楚，沒有細細研究vcs
Hi,
you just need to set VCS_TARGET_ARCH=amd64 to run full 64-bit simulation
