Hi all,

How to rum Monte-Carlo Simulations in Cadence Virtuoso Analog Design Environment...? I'm using UMC180 Technology on IC616. The model files are been loaded to ADE automatically because of *.il file at schmatic level. I'm able to locate Monte Carlo model fles @ /Models/Spectre/Monte_Carlo. Since in my design I'm using only NMOS & PMOS, I've to use only

mm180_reg18_v124_mc.lib.scs
mm180_reg18_v124_mc.mdl.scs
mm180_reg18_v124_mc_corner.lib.scs
mm180_reg18_v124_mc_statistical_m.mdl.scs
mm180_reg18_v124_mc_statistical_p.mdl.scs.

Kindly let me know how to run MC @ ADE-XL..?

Am i need to modify anythind in the above said files since it saying..

ERROR (ADEXL-5052): Monte Carlo run stopped because no statistical data generated for the test

Follow the attachments for my concern......

Thanks in advance.......



 

Hi All,

I'm able to run Monte-Carlo Simulations using gpdk180. I'm doubting that in gpdk model files
Process parameters
Mismatch parameters
are defined. Whereas the same are defined to be Zero by default @UMC180.

Kindly let me know how to work it out.
 

Hi All,

Add "* parameters sigma = 3* " in
MM180_REG18_V124_MC_STATISTICAL_P.mdl.scs
file.

The issue has been resolved....
