How to Add DRAM Clock to Project for LabVIEW USRP 2954

  • USRP-2954

Issue Details

I know how to use DRAM, but on the USRP I don't find the DRAM clock, and using add base clock don't add it to the project.

Solution

Not every target has DRAM clock exposed.

Use the derived clock for the SCTL where you are running DRAM processes.
I believe USRP DRAM has 256bit interface and >= 125MHz clock.

Snippet from an old project for USRP 2955: DRAM FIFO Mem IDL was able to compile for Data Clock at 200MHz.
