Which version of Modelsim are you using?

Modelsim Altera Start Edition should know about the lpm library already, type

vmap

to see the library mappings.

For example Modelsim 6.6c has the mapping:

# "lpm" maps to directory C:\software\altera\11.0sp1\modelsim_ase\win32aloem/../altera/vhdl/220model.

Perhaps you have managed to mess up your environment setting?

If you are using a full-edition version of Modelsim, then you need to compile the library. I can help with that, if that is the case.

Cheers,

Dave
