Dear Sir, When I run the Alliance 4.0.6 for behavior capture and simulation , I got a problem. First I ran the "asimut -b -c addaccu" command and it works fine. Then I ran "asimut -b addaccu addaccu specifications" and it is fine and generates specifications.pat file. Then when I ran couple other commands, It generated the core.vst file and then addaccu.vst file and everything work ok until I ran the command "asimut addaccu addacccu schema". I got an error message " ***MBK error*** can't open file ms_y.vst ". I am wondering what is wrong ? Up to this point I didn't get a schema.pat file in my directory. Thank you for your time Sutarto __________________________________________________ Do You Yahoo!? Yahoo! Mail – Free email you can access from anywhere! http://mail.yahoo.com/
