Problem in using Hierarchical Blocks in OrCAD Capture 10.5

Dear All,

I am using OrCAD 10.5 Schematics Capture tool and my design requires
same circuit to be used twice on the board. So I created a hierarchical
block and pasted two instances of this hierarchical block in order to
have same circuit repeated twice. But I am getting error while
generating the netlist as reference designator remains same for the two
instances of the circuit. For e.g if I have capacitor C1 in one
instance (hierarchical block) then the reference designator
corresponding to the same capacitor in the other instance (hierarchical
block) is also C1.

Please let me know of the solution. Needless to say, I would be very
thankful.

Regards,
Mohit
 
Take a look in the help at the differences beteen simple and complex
hierarchy. If your only using the block twice I would suggest simple
hierarchy.

How would the pcb designer know which C1 you wanted connecting? You must have
different component references if they are to go on one pcb.

It should be showing something like, for example...

C_HB1_C9

and

C_HB2_C9

Perhaps, when you copied the block, the "HB" designator didn't change?

Or it could be that CRAP called OrCAD Capture... I use the old
original MicroSim PSpice Schematics.

I love to cook with wine. Sometimes I even put it in the food.
 
If you try to open one of the sub-sheets directly, you'll notice that
it's asking which instantiation you want to open; it's keeping track of
the annotations seperately.

You need to re-annotate your design. Do an 'unconditional' update.
 
Dear All,

Thanks for your prompt responses. The problem was solved by doing
unconditional update first and then reannotating the design.
