[liberate] FAILED TO GET MOS MODEL FOR 'XMP32_0'!

I am trying to characterize a standard cell library, but liberate gives me the following errors. The point is that some of the standard cells can pass while the other such as MUX4D8 can not. As shown in the blow, MUX4D8 can pass the timing test ( can be checked in the deck ), when it comes to power, error occurred.

*Error*

The model they used is the same (same type NMOS and PMOS) and been set in the char.tcl.

Do you have any suggestions for this problem?

Thank you in advance!

Hi Sherryshe,

Which Libeate version are you using?

Do you have -extsim spectre in char_library command?

Is the line for instance XMPM32_0 complete and correct in syntax?

Did you run the saved deck for the failed arc? Please use extsim_flatten_netlist=0, ski_enable=0, extsim_save_passed/failed=deck for this debug.

Regards,

Guangjun

Hi Guangjun,

The problem was solved by setting extsim_flatten_netlist and ski_enable = 0.

Thank you for your help!!

Neither of the two is recommended for production flow.

If you are using latest Liberate release, and either or both parameters must be used to avoid the issue, please contact customer support for furtehr investigation.
