simulation problem with sdf

vsim-sdf-3251

it is the post-simulation after P&R completed.

when i do post-simulation, a error occurs which interrupt the simulation
the log lists here:
# ** Error: (vsim-SDF-3445) Failed to parse SDF file "D:/test/move/moving_picture.sdf".

i have no idea about what problem SDF file may have?
help me please!

Does the file/path valid? Do


It is also be possible that your SDF file has some syntax error, how was this SDF file generated?

Use the verror utility, here is what it says for this error:

$ verror 3445

vsim Message # 3445:
One or more problems occurred during parsing of the SDF file. Look
earlier in the transcript for error messages that indicate what the
problems are.

i have checked the path again and it's ok

sdf is generrated after sta with paramistics file using primetime
does simulation tool can report some indications if sdf file has some syntax errors?

In compared with sdf generated after systhysis, there are a litter changes just like clock buffers models and no any other differences

and the gate level-simulation is ok now, so what should i check the protential error?

weather the error is caused by the process of P&R or not and i have no experience for this

thanks, aji
