[PCB_FORUM] Re: varient Bom

Hi group,

We did get the varient bom to work 90%.
Meaning, I could run Tools Varient Bom, create two other secondary models. Model_a and Model_B. Select parts to change values and can select Do Not Install which adds a DNI property to the part to remove it from the desired secondary bom. 

I created Bom.rpt by selecting Varient Bom in BOM output dialog box.
Thus creating three bom's listing the modified values and any DNI parts are removed from that bom. 
1. BOM.RPT
2. BOM_MODELA.RPT
3. BOM_MODELB.RPT
ALL IS GREAT!!! Until we want to install a component in a secondary model that is NOT installed in the primary board bom. We have BOM_IGNORE property on all schematic symbols not populated in the main model. 

*QUESTION: Using varient BOM
How can I have a component that is NOT populated in the primary or base mosel to now be populated in a secondary model? 

*regards,
Mark*

I'm sorry that isn't working. You may have to contact Cadence. As far as
I
know there isn't anything special we have done to make this work. And we
are also
using 15.7.

When you look in the .csa files under the sch_1 directory. Can you find
the
property BOM=NONE or BOM=1? If these look different that may be the
problem.
But if all else fails open a case with Cadence. They should be able to
answer this.

Hello again Dave,
I tried that too but only one bom .rpt output. Here is what I did....
1. I added property BOM=1 by Property name BOM, type 1
2. Packaged the design: 
3. Ran BOM from Concept menu / Tools / Packager Utilities / Bill of
Material


Questions???
1. Do I have to set anything in the packager to pass BOM property? 2. Do I have to set anything in the BOM Template file? 
3. How does it know to create 2 BOMs?
4. We are using Concept HDL v.15.7.....How do I know which program it is
running? (i.e. cnhdlbom)

Your suggestion sounds great, but I need to know how to get it all set
up to output both boms.

Thanks again for your feedback.
Does anybody else use this method?

Regards,
Mark

        Hi
        
        I stirred you wrong. I needed to be more specific. The property
needs to
be BOM=1 and BOM=2 etc. or BOM=NONE. Then the program cnhdlbom should 
create the
separate files.

        Hi Dave,
        Bom_Ignore is a cadence property that can be used to remove
parts from a
        BOM.
        How do you get Bom_1 and Bom_2 to create two different BOM's.
        We just tried it and only one bom.rpt was generated.
        Added property and value of TRUE.
        
        1. We need to have bom_ignore for the "main model"
        2. How do we get "Not installed" parts removed from the 2nd
model?
        3. Then we need different values for components to package into
        different bom's.
        
        Is there some BOM setup that has to be made in order to creat
more than
        one bom?
        
        Thanks,
        Mark

                What we have done in the past is use BOM_NONE for the
parts you don't want in the BOM. And BOM_1 for the first version and BOM_2 for the second version and so on. 
                
                When you run the BOM output it will create separate BOMs
1,2 ....
                
                Hope this is what you are looking for.

                Does anyone use the varient bom successfully?
                We use BOM_IGNORE for do not install components.
                
                We want to use a single schematic and .brd with three
separate model builds. 
                Meaning three different population and component values.
                
                Example:
                Model         |   bom_ignore   |   Value (R1)   |
                Model A     |   TRUE            |    1K             |
                Model B     |   FALSE          |     2K            |
                Model C     |   TRUE            |     3K            |
                
                In the past, we have done the following:
                1. Add BOM_IGNORE in schematic for any nopops in main
model.
                2. Any other model nopops or value differences are noted
in a tble on the schematic. 
                3. PNP data is for main model only.
                3.a. Secondary model PNP data must be modified manually
per table in schematic. 
                4. List nopop and value differences in assembly drawing.
(Manually)
                
                Any suggestions are welcome!
                
                Thanks,
                Mark
