Cannot read BRAM input signals

Cannot read BRAM input signals

Closed this issue 12 years ago · 2 comments

For some reason XPS thinks that the BRAM_Din signals do not have a load and therefore does not route it. I am trying to input RUNTIME and OUTPUT_CYCLE signals into test_core.vhd. Everything works fine in ModelSim simulation but it doesn't synthesize these signals in XPS. I really don't know how to fix this bug!

Okay routing problem is fixed..i.e. XPS now routes the BRAM_Din signals. However the problem still exists..for some reason my core cannot read in the values being sent to the BRAM although as said it works perfectly fine in simulation.

Sorry for the false alarm...It was my input data being sent in the wrong way. There is no problem in reading BRAM data.
