Hi, I think that SCR for version 4.0.6 has errors. I've tried to convert 2 .vbe files to .vst files. They both were simulated using asimut with no problems before. As soon as I test the .vst file with the same pat files, I get unexpected values at the outputs? I did the same for addaccu, as addaccu already has a .vst file I ran that through asimut with addaccu.pat and simulation was successful. I created a .vst file for addaccu using the addaccu.vbe file provided and tested the output .vst file. Asimut could not continue as it said it had too many errors. Surely that means that scr isn't working right? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
