Trying To Block RAM

Sign in to follow this Followers 1 Possible to synthesize a "byte-enable" function for the RAM blocks? Please check that the RAM contents is read synchronously." Am I doing something wrong? As far as using the block memory in VHDL, the Block Memory Generator will generate a template I believe which shows how to hook it up. Side-note: you don't use the output pipeline register. http://gsdclb.org/trying-to/trying-to-rid-computer-of-host-block-virus.php

You are going to want to set them to some value when WriteEnable(0) and WriteEnable(1) are true, not just when they are false. This generates a level of uncertainty. The second peace of code is what I have been working with which gave me many errors which I posted in another thread multi-driver net found.

If you can deal with a few cycle latency between reads and writes, you can implement byte-enable in logic around the BRAM, but it would really matter on your application design I just added some (*dont_touch = "true" ) 's to all of the output registers of all of the brams and it seems it is working. Summary: inferred 32768 D-type flip-flop(s). Same result in all of them.
