ncelab W,SDFRDE error problem

I have problem while post simulation compiling with ncverilog.
I can't envalop sdf file into post gate net, and ncv did not give any log.

Ncverilog.log message is next.

ncelab: *W,SDFRDE: Read error for default code, skipping annotation of FG003N_worst.modify.sdf.X.
ncelab: *W,SDFRDE: Read error for default code, skipping annotation of FG003N_worst.modify.sdf.X.
ncelab: *W,SDFRDE: Read error for default code, skipping annotation of FG003N_worst.modify.sdf.X.

sdf_annotation log is next.

Annotating SDF timing data:
Compiled SDF file: FG003N_worst.sdf.X
Log file: sdf_annotation.log
Backannotation scope: tb.CHIP
Configuration file:

ABSOLUTE PORT: tb.CHIP.FG003N_U_compressor_compression.g64941.A0 = (7)


Can anyone know why occur this error?

Hi, does this tell you anything more ?

nchelp ncelab SDFRDE

Thanks for reply.

I looked up nchelp already.
Nchelp message is next.
W,SDFRDE warning happend when ncelab can't parse sdf.X annotaion.

But I don't understand sdf.X reading error in spite of compiling sdf.X successfully.

Hi, I sent this question to Cadence's Verification Forum.

Here is the reply:

"The times I've seen this error in the past have all been due to a corrupted SDF file.
The solution has been to delete the .X file and get the process to start from the original text .sdf file again."

Thanks for reply. Your reply is a great help to me.

furthermore ,you can try to check the sdf first incase you lost your time to do simulation!
