Test bench

--- Quote Start ---

Hello sir

can you please tell me how to create and run test benches in QUARTUS II

--- Quote End ---

You don't. Rather, you create and run a testbench in Modelsim (Altera Starter Edition). Here's an example testbench to get you started (modelsim_example.zip):

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

The library is located in:

$env(QUARTUS_ROOTDIR)/eda/sim_lib

You can set it up via:

vlib lpm

vmap lpm [pwd]/lpm

vcom $env(QUARTUS_ROOTDIR)/eda/sim_lib/220pack.vhd

vcom $env(QUARTUS_ROOTDIR)/eda/sim_lib/220model.vhd

(I'm just typing this from memory, so if it doesn't work, let me know, and I'll check for the correct syntax).

Cheers,

sir

i have typed as u said in the command promp of modelsim

my pwd is c:\ Modeltech_pe_edu_10.0d\examples were my project is stored

vlib lpm

vmap lpm c:\ Modeltech_pe_edu_10.0d\examples/lpm# Modifying C:/Modeltech_pe_edu_10.0d/examples/voq_switch_2.mpf# ** Error: (vmap-20) Cannot access file "c:Modeltech_pe_edu_10.0dexamples/lpm".# No such file or directory. (errno = ENOENT)

this are the errors i get.......

thank you

if you have spaces in your path, you need to enclose it in quotes ""

you can also map to a library right right clicking in the libraries window and selecting "add library -> map to existing library"

You need to use forward slashes in Tcl (and no space as Tricky commented)

vlib lpm
vmap lpm c:/Modeltech_pe_edu_10.0d/examples/lpm
