Problem with Sign-off option in EDI

Hello everyone,

I'm trying to use the sign-off option available in EDI for optimization and also timing report. Everything goes well till after post route stage, however I somehow trapped in an iterative loop which cannot get out!

After setting the RC Extraction mode to be in sign-off level (coupled true) and having the timing analysis mode with OCV ( Delay Calculation Options: engine=aae signOff=true SIAware=true(signoff)).

During optimization I encounter:

**ERROR: (ENCOPT-7055): use setDelayCalMode -engine [feDC | signalStorm] -SIAware false before running optDesign -postRoute -signoff.

and when I want to get a timing report  I get the following:

"ERROR: (ENCESI-2017): There is no coupling capacitance found in the design. Use setDelayCalMode -siAware false to perform base delay analysis. SI analysis requires the parasitics database to contain coupling capacitance. To perform SI analysis, use 'setExtractRCMode -coupled true' prior to extraction or load a SPEF with coupling capacitance and re-run."

the last one is a bit confusing since I already set the -coupled option to be true and it works fine in post route stage (without sign off option). Any idea where is the problem?
