Hello,

I have been trying to simulate a xilinx library into my working directory but i am getting the following errors. Does anyone have any idea to what i should do?

It compiles for awhile and then gives me the following error: too long to put the whole list...so I'll put where the error starts!

vcom -87 -work unisim C:/Xilinx/vhdl/src/unisims/unisim_vital.vhd

Plz check the libraries you have included in your vhdl top file. I think that should work...
