Room numbering in hierarchical design

[mgulin]

Hi everyone,

I'm using a hierarchical design, and I have a problem with room numbering. I have one sheet that is used in two places, something like in the attached image.

Now, when I compile the project, the rooms are named as follows:

RC_ADCIN1, RC_ADCIN2, ..., RC_ADCIN20, RC_FPGA_IO21, RC_FPGA_IO22, ..., RC_FPGA_IO32

I would like that RC_FPGA_IO rooms go from 1 to 12. Do you know is this possible in Altium?

I think you need to type 1..12, but I have no way to verify this now.

I think the problem is that you're using the same base sheet for both repeated sheet symbols, and I guess it's a quirk of the way Altium compiles the project that it creates unique suffixes across both repeated instances.  I bet if you created a different base sheet for the IO filters and then used that in a repeated instance it would work the way you want. 

If you really want to use the same sheet in both places, you might be able to create an RC sheet, then place a single instance of that in an ADCIN sheet, then place and repeat the ADCIN sheet.  Do the same thing with an IO sheet, then turn class generation off for the RC sheet and you MIGHT be able to get the rooms to generate the way you want.
