[PCB_FORUM] Re: Exporting and Importing of SI Models

Dear,

 

Thanks, but how about export/import specific refdes with SI model to another board file

 

Here is what I’m up to, if I have 10 resistors having the same package symbols and only 2 of it need to have an SI model, I want to change the 2 resistor in the other board file without changing the other 8

n        I did not changed the whole set of package because I want to keep the other as normal net

 

Anyone tried this? Or a skill file perhaps

 

Thanks

Aries ,

The topology files do not have the si modeles in them they are just electrical rules and scheduling for nets/xnetx, the model are stored in the device.dml file, if you go to analize >si/emi sim >models, and select auto setup , most of the discrete will be auomaticaly assigned from the cadence default, you can also dump the models from a brd by going to analize >si/emi sim >model dump/refresh, this will create a file called board_name.dml, then you can add this to your device library in analize >si/emi sim >library, select Add existing library and browse to that file

you may still need to run analize >si/emi sim >models, and select auto setup to assign the models

hope that helps

Migs,

 

Thanks for the reply.. But can you give me some details how to do the process

 

Here is how I’m doing it now

From File with XNET

1.       in Constraint Manager

甲、    File Export à Electrical Cset

*** At this point I have an output of *.top files

 

 

In the File without XNET

1.       set up the correct path for my *.dml models, in User Preference Signal_Analysis Folder à signal_install_dir

2.       in Constraint Manager

甲、    File Import à Electrical Cset

*** I have selected the *.top file previously generated

 

Then check my nets.. But still they are not converted to XNET

I’m using Allegro v15.7

 

 

Thanks

Aries,

All you need is the *.top(topolgy model) and the *.dml(ibis models).     Also make sure you are pointed to the same SI libraries.

Dear ALL,

Anyone knows how to merge or export/import SI Models from one board file to another? (Having the same board file but just different revision)

Or I just need to re-setup everything in the Database Setup Advisor – SI Models

 

Thanks
