how to load a sdf file in modelsim 5.7g

[s3034585]

Hi guys
i am trying to load a sdf file for one of the components in my design but i am getting error saying that the instance is not found...

i have a top level entity named top_entity and i have a test bench for this as top_entity_tb.

top_entity has 2 components called comp1 and comp2 instantiated in it.

and i have generated a post place and route model for comp2 and i want to load it and simulate it.

can any one tell me how to do it...

i read model sim manual and found out that


it should be like this

vsim -sdfmax /top_entity_tb/top_entity/comp2=comp2.sdf top_entity
but when i give this command it gives me a error saying that comp2 not found


can any one please let me know about it
thanks in advance

Hi,
Search the top module file name in .sdf file. There file path may be wrong.Please check.

If your using Quartus II the file is *.sdo

Hi,
Very likely you have used the module/entity name than instance name. Is comp2 an entity name? What's its instance name when it is instantiated inside:

top_entity_tb/top_entity/

Use that name.
