Hello,
I'm currently trying to build a design in the ZC702, where it is connected to 2 (two) FMC30RF, one in each FMC LPC port, but now I'm having some issues concerning the design:
I started with your StellarIP design, and edited it to have the two boards; after that, I opened ISE, and after some tweaks to the VHDL to implement all like I wanted, the ISE design tells me that the design is unfeasible due to the overmapping of RAMB36E1.
Basically, I just duplicated the FMC30RF board in this design, and the quantity of RAMB36E1 used in the original project doubled, turning the design impossible. With this, I assumed that all the RAMB36E1 is being used just in the FMC30RF..
In the documents you provided, you say that is possible to make a MIMO architecture, and I wanted to ask you some things:
1) What is your recommendation regarding such a design? Should I use a multiplexer to receive information from the two boards or should I use just one axi bus? Or Should I just follow a completely different approach to this problem?
2) Is there any way I can change the utilization of all the RAMB36E1 provided in your design? For example, turning the RAMB36E1 to RAMB18E1 or any other thing?
3) Do you have any documentation/tutorials/examples regarding this "one ZC702-to-two FMC30RF" design I'm trying to build?
Thank you,
Joao
