DE2-115 and HSMC daughter card

[FPGA_FR]

Hi,

I am currently doing a project using a DE2-115 (Cyclone IVE) with an HSMC-XTS daughter card. I want to assign output from a simple digital circuit (even a debounced switch as a start) to the SMA output ports of this daughter card. The technical difficulty I encountered is that the HSMC-XTS daughter card (according to the Terasic Website) is normally intended to evaluate the performance of transceiver-based host boards with HSMC interface, specifically Cyclone IVGX FPGA with integrated transceivers. However, Cyclone IVE does not have these integrated receivers. Yet because of the straightforward design of the HSMC-XTS daughter card, I am pretty sure I can exploit these SMA connectors as general-purpose outputs.

I think I should provide a specific pin assignment in Quartus to assign an output to a given SMA port, but despite numerous tests I have failed so far. The user manual labels the ports of interest HSMC_TX_P[i] with i=0,...,3. However, they do not appear as such in the pin assignment editor. They are also physically marked as pins J9, J13, J17, and J21 on the daughter card. Note that I did not manage to use the HSMC_TX ports on the daughter card, but I succeeded in using the clock output (HSMC_CLKOUT_P2, pin J25 on the daughter card).

If anyone has experience with this type of daughter card or ideas on how to proceed, that would be great.

Thank you !

Hello

Welcome to INTEL forum. The DE2-115 (Cyclone IVE) Development Kit Board belongs to Terasic. You can find the User Manual, Daughter Card Demos, CD-ROM in https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=139&No=502&PartNo=4#contents

It would be better if you could contact Terasic for enquiry related to Terasic board. https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=12&No=20        

Please accept my apologies for not being able to assist you fully as this is out of my expertise.

Thank you very much for your feedback !!

I did receive some feedback from Terasic and it is indeed not possible to exploit these particular SMA connectors as general I/O.

I will have a different solution.

Thank you again for all the supporting message and feedback in this post !

Best wishes,
