sram2ddr not working in simulation

[Dr. P]

Hi, I am trying to run the SRAM to DDR component in simulation. I set up a Vivado project and imported the SRAM to DDR component.  Then set up a clock for simulation, then wrote a simple testbench. I have been trying everything I can think of for several hours, but I must be missing something.  I'm getting a couple of warnings, but they don't seem related. I'm at a loss. Here is a link to my project: RAM4.zip

Thanks in advance!

Hi @Dr. P,

Here is SRAM to DDR Component documentation that should help with your project.

1) Are you planing on using a specific development board?

2) Here is the getting started with microblaze  tutorial for the Nexys 4 DDR that uses the SRAM to DDR component.

thank you,

Jon

Thanks.  I have been through the documentation an the SRAM to DDR Component several times, and even tried using the top module that was posted in the forum.  It gave exactly the same results as my own code. I will be using a NEXYS A7, but I am just trying to get everything working in simulation right now.  I looked at the microblaze link you provided, but it did no good. Does the SRAM to DDR Component even supposed to work in simulation, or is it something that only works on the hardware?
