Dear sir : I'm a student at Cairo univeristy. I'm currently learning the VLSI design. I have dounloaded the following S/W from the Alliance site "alliance-4.0.6-cygwin-b20.exe" under windows 98. I have faced the following problems : 1- After installing alliance I made run for the alliance console from windows. When this file run it gives me the following error "out of environment space" it gives me this error several times and stops at the dos prompt. 2- when i run some alliance binary files it gives me the message that the following DLL file is missing "LIBICE.DLL". Can any one help me to solve this problems and make alliance working. Or there is another thing i must install. With my best regards Yasser El-haddad
