Errors in simulating verilog models in ModelSim

simprim?

Iam using Xilinx tool ISE6.1 and linked ModelSim SE 6.1a to Xilinx tool
as my simulator tool , now I have 4 icons in my process view in ISE ,
Simulate behavioural model ,
simulate post translate verilog model ,
simulate post map verilog model ,
and simulate post P&R verilog model

when i click any of these icons the modelsim starts ... for the first
one (simulate behavioural model it works correctly) but for the other
three the mdelsim gives me an error :

** Error: (vsim-19) Failed to access library 'simprims_ver' at
"simprims_ver".
# No such file or directory. (errno = ENOENT)

I searched over xilinx directory and found directory called
'simprims_ver' , so I map this directory into the modelsim.ini file ,
now the error message :

** Error: (vsim-25) Invalid ModelSim library "my directory path". No
_info file found.
# No such file or directory. (errno = ENOENT)

when I opend this directory , I realy couldn't find _info file ??

can you give me a hand , thanx

Re: simprim?

simprim is the simulation primitives library. U can find it in xilinx folder in your system.U compile it and add to ur project.

Added after 10 minutes:

U need to compile the simprim codes to have _info file .U'll have that in ur work library then.
