RB 02:39 PM FPGA Development: RE: Input/Output interfacing

Thanks Mike,
I was able to export the signals I wanted and they now show up in Pin Planner.
Is it in general ok to retask signals in the 5CSX_IO class?
For example, I see that on Module Pin Number 60 corresponding to CYCLONE pin AH2... Rich Bagdazian

The FPGA ball numbers can be mapped to the edge connector via Table 7 in the "datasheet":http://www.mitydsp.com/images/upload/File/MityARM-5CSX-Datasheet.pdf.

RB 07:03 PM FPGA Development: RE: Input/Output interfacing

Also, I don't know if I have seen a file which shows which physical pins on the FPGA end up on which physical connectors/pins on the carrier board.
Can you point me in the right direction?
Thanks! Rich Bagdazian

Hi Dan
Yes, I have done exactly as you described.
I haven't worked with the Pin Planner as of yet, so I'll take a look at that tomorrow.
So if I understand correctly, after I do a successfule Analysis and Synthesis step, the signals... Rich Bagdazian

Hi Richard,
I'm guessing you've created a component with a conduit for these external signals and you've exported this conduit through qsys to your top level entity, is this assumption correct? If it is then you can use the pin planne... Daniel Vincelette

RB 04:47 PM FPGA Development: Input/Output interfacing

I have built a custom component in QSYS as a memory-mapped avalon slave and been able to interface it
correctly so that I can communicate with it via the ARM processor as expected. This module also provides
some I/O signals that I want... Rich Bagdazian
