Hi,

I have three questions,
1.I try to find VHDL codes,then put in my Encounter RTL
Compilier to do synthesis,but the terminal shows me some error messages
as following:

rc:/> Setting attribute of root '/': 'lib_search_path' = /opt/cadence/local/osu_stdcells/lib/tsmc018/signalstorm
Freeing libraries in memory (osu018_stdcells.lib)

Setting attribute of root '/': 'library' = osu018_stdcells.lib
library ieee;

Error : Parsing error. [VLOGPT-1] [_read_hdl]
: in file 'alu_rtl.vhd' on line 2, column 7.
Failed on _read_hdl alu_rtl.vhd


Why does not the library support the ieee of VHDL?
Would you please tell me how to resolve it?Thank you

2.Would you please tell me how to install and set Mentor Graphics Modelsim
SE 6.5 on Linux OS?Which commands do I need to type?

3.Does anybody tell me how to generate the SDF file in simulation of Modelsim SE
6.5a?Thank you!
