Assura_RCX_Adv_Process?

[Gerard Wienk]

For our current technology we need Cadence Assura 3.1.5 to do parasitic
extraction.
I get the following error when I try to extract parasitic R or RC.

Successfully created RCX script
'/misc/icenas/gerardw/cadence/linux/c065/lvs/fringecap/rcx.sh'
Checking out 1 license for Assura_RCX_Adv_Process 3.10 ERROR (LM-30)

"Assura_RCX_Adv_Process" (run 'lic_error -30' for more information)
*WARNING* Failed to obtain license for Assura_RCX_Adv_Process
*WARNING* ERROR (LM -30): license server ("icehp2") does not support
feature "Assura_RCX_Adv_Process" (run 'lic_error -30' for more
information)

C-only RCX works fine


With older technology and previous versions of Assura I was always able
to do parasitic extraction of R and C.

Are there some serious changes in Assura 3.1.5 ?

I get the software from Europractice, but they seem to have no clue what
my problem is. I also could not find anything on this matter on sourcelink.


Can anyone shine a light on this matter?

Regards,

Gerard

This is an excerpt from solution 11233382 :

The presence of any of the the following Advanced Nanometer features in the
process file or p2lvsfile needs an Assura_RCX_Adv_Process license:

a. Temperature coefficient as a function of metal width (TCW)
b. Resistivity (rho) as a function of width and spacing
c. Erosion as a function of density and width tw

Please contact your PDK vendor to check if they can provide a RCX Technology
directory that does not use any of the above features. If you need to use the
above features, you will need to have an Assura_RCX_Adv_Process license.

From complete details on Assura license requirements, kindly refer to the latest
Assura Developer Guide->Appendix A (Licensing Information)

Regards,

Andrew.
